74,941,689 | 2 | null | 74,941,519 | 0 | null | Using [IntersectionObserver](https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API) is your go-to here. Thanks to it, you will be able to set various behavior, fetch content and allow for interactivity regarding the other "date cells".
The [useIntersectionObserver composable](https://vueuse.org/core/useintersectionobserver/#useintersectionobserver) is a good candidate for such a purpose.
---
Only displaying what is currently visible can also be helpful, so that you don't have too much content in the DOM. This [may help](https://github.com/Akryum/vue-virtual-scroller) but can also be done yourself (check the source code there).
---
I'm not sure why your list needs to be re-rendered but maybe consider not nuking the whole thing and applying some modifications at the given locations.
Or use a [memoization approach](https://vueuse.org/core/usememoize/#usememoize), depending on what you need to memorize it may be quite quick to implement yourself.
With the given approaches listed above, you may not even need to remove dates from your list, just hide (CSS) or let it off the screen. Aka rather than having `let datelist = [yesterday, today, tomorrow]`, consider having `let datelist = [..., x , y, today, z, a, b, ...]` each time you reach a boundary.
---
TLDR: for your constraints, you can pick only 2 from the 3.

Here is an example of using IronPython in a C# Windows Forms app:
1. Create a Windows Forms application.
2. Install IronPython nuget package.
3. Add using IronPython.Hosting; statement to the using statements.
4. Drop a TextBox on the form (textBox1)
5. Drop a Button on the form (button1)
6. Double click on button and add the following code for the click handler: private void button1_Click(object sender, EventArgs e)
{
var engine = Python.CreateEngine();
var scope = engine.CreateScope();
//You can also load script from file
var source = engine.CreateScriptSourceFromString(
"def hello(name):" + "\n" +
" result = 'Hello, {}!'.format(name)" + "\n" +
" return(result)",
Microsoft.Scripting.SourceCodeKind.Statements);
var compiled = source.Compile();
compiled.Execute(scope);
dynamic hello = scope.GetVariable("hello");
var result = hello(textBox1.Text);
MessageBox.Show((string)result);
}
7. Press F5 to Run the application, enter a text, and click on the button. The function will run and you will see a message box saying hello.

Looking at your print I suppose you are using pgadmin or some simmilar GUI, on the case of pgadmin if you click on the column and select the import\export data... option, you will open a windows where you should select "import" and then, on the upper windows menu, click on "columns" and exclude the "ID" or any other auto-increment, this slution also needs you to remove the csv column as well.

74,942,431 | 2 | null | 74,930,784 | 1 | null | I've been trying to solve this issue myself for some time, and It seems the only way to automate disabling the script icon gizmo is by disabling the icon gizmos of your specific `MonoBehaviour` through reflection.
Here's where I found my solution. The last answer by Acegikmo gives a concise method that solves the issue perfectly.
[https://answers.unity.com/questions/851470/how-to-hide-gizmos-by-script.html](https://answers.unity.com/questions/851470/how-to-hide-gizmos-by-script.html)
```
static MethodInfo setIconEnabled;
static MethodInfo SetIconEnabled => setIconEnabled = setIconEnabled ??
Assembly.GetAssembly( typeof(Editor) )
?.GetType( "UnityEditor.AnnotationUtility" )
?.GetMethod( "SetIconEnabled", BindingFlags.Static | BindingFlags.NonPublic );
public static void SetGizmoIconEnabled( Type type, bool on ) {
if( SetIconEnabled == null ) return;
const int MONO_BEHAVIOR_CLASS_ID = 114; // https://docs.unity3d.com/Manual/ClassIDReference.html
SetIconEnabled.Invoke( null, new object[] { MONO_BEHAVIOR_CLASS_ID, type.Name, on ? 1 : 0 } );
}
```
You just need to call the method `SetGizmoIconEnabled` from anywhere for the Type of your `MonoBehaviour` and it should work.
---
The alternative is to manually find the Gizmo dropdown menu in the Scene view and disable the script Gizmo from there:

74,942,620 | 2 | null | 74,369,892 | 3 | null | The Flutter will always render the children of the Stack in order, what means that the last widget of the Stack will be in front of every other widget, and that is why the purple side (the last child of the Stack) is always visible regardless of the movement you do.
To simulate a cube you will have to change the order of the cube's sides accordingly to the rotation of the cube. To change the order, you will have to store all the sides in an array and pass this array as the argument of the Stack:
```
class _CubeState extends State<Cube> {
List<Widget> sides = [];
final side1 = Transform(
key: const ValueKey("side1"), // you must use a key to allow flutter to know that a widget changed its order
transform: Matrix4.identity()..translate(0.0, 0.0, -100),
alignment: Alignment.center,
child: Container(
color: Colors.amber,
child: const FlutterLogo(size: 200),
),
);
//... the other sides follow the same logic of the side1
@override
void initState() {
super.initState();
sides = [side1, side2, side3, side4];
}
void update(Offset value) {
setState(() {
// I recommend to normalize the offset to be always between [0, 360)
offset = Offset((offset.dx + value.dx) % 360, (offset.dy + value.dy) % 360);
sides = [side1, side3, ...] // change the order of the sides here accordingly with the new offset value. This is the hardest part. For a cube where you want to render all the 6 sides, you will have to perform a lot of calculations to know which side is in front of which.
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: Stack(
children: [
// The rendered cube is inside the `Center` widget below
Center(
child: Transform(
key: const ValueKey('cube'),
transform: Matrix4.identity()
..rotateX(-offset.dy * pi / 180)
..rotateY(-offset.dx * pi / 180),
alignment: Alignment.center,
child: Stack(
children: sides,
),
),
),
// The gesture recognizer that will receive the movement of the mouse is inside the `Positioned.fill`
Positioned.fill(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Expanded(
child: GestureDetector(
onPanUpdate: (details) {
update(details.delta);
},
child: Container(color: Colors.transparent),
),
),
Text('x: ${offset.dx} y: ${offset.dy}')
],
),
),
],
),
);
}
```
Note that you need to pass an unique key to every widget in the Stack to make it possible to Flutter identify uniquely every widget (you can see more about Keys in [https://www.youtube.com/watch?v=kn0EOS-ZiIc](https://www.youtube.com/watch?v=kn0EOS-ZiIc)).
I made a simple example below with a cube of 4 sides. To do the same in a cube of 6 sides will require more math, but I think I gave you enough knowledge to you figure it out that by yourself.
[https://dartpad.dev/?id=3698b3013fe7189d3c3c063d088cf69a](https://dartpad.dev/?id=3698b3013fe7189d3c3c063d088cf69a)
### How to capture the mouse movement independently of how the cube is rotated/transformed.
If the `GestureRecognizer` has the transformed cube as its child, the movement of the mouse will capture the original cube's side that was being show at the beggining (the blue side in my example), thus depending on how the cube is rotated, if the blue side is not visible anymore, the mouse will not be captured anymore. To solve that we have to split the mouse capture logic of the cube's rendering.
There are many possible ways, one of those is to render a `Stack` (to make one child be in front of another child, creating multiple layers). The underlayer will be used to render the cube and the overlayer will be used to capture the mouse movement (this layer needs to be transparent to don't affect the visualization of the cube).
I did that with the cobe below:
```
Stack(
children: [
Center( // This is the underlayer that renders the cube. It will be always in the center of the screen.
child: Transform(
key: const ValueKey('cube'),
transform: Matrix4.identity()
..rotateX(-offset.dy * pi / 180)
..rotateY(-offset.dx * pi / 180),
alignment: Alignment.center,
child: Stack(
children: sides,
),
),
),
Positioned.fill( // This is the overlayer that receives the mouse/finger movement. It has to be a `Positioned.fill` if you want that all the available space can be used to rotate the cube.
child: GestureDetector(
onPanUpdate: (details) {
update(details.delta);
},
child: Container(color: Colors.transparent), // We need any widget that actually renders pixels on the screen and that can have a size. If not, the `GestureRecognizer` would have size zero and would not work. The colors is transparent to allow the cube (that it is in the underlayer) to be visible.
),
),
],
)
```

74,943,040 | 2 | null | 74,942,744 | 0 | null | So you are using the Field Calculator to compute the values for Column C from the values of Column A and Column B.
Note that QGIS Feature attributes have types they could be either integer, float, or text. Assuming your Column A and Column B are integers, then Column C would also be an integer column, therefore the value `'???'` would not be acceptable as this cannot be converted to an integer value.
One common approach to this is to reserve a specific value from the integer range as an additional INVALID DATA value. For instance if all your valid values are positive you could use `-1` as your INVALID DATA value.
Then your code could look like this:
```
if( ("PUNTS INICIALS ed50_EQM1 C d" is NULL) or ("PUNTS FINALS ed50_EQM1 C d" is NULL),
coalesce("PUNTS INICIALS ed50_EQM1 C d","PUNTS FINALS ed50_EQM1 C d"),
if("PUNTS INICIALS ed50_EQM1 C d"="PUNTS FINALS ed50_EQM1 C d","PUNTS INICIALS ed50_EQM1 C d",-1))
```
Note that `coalesce()` can be used to handle the case when one of the values is NULL.

74,943,288 | 2 | null | 4,553,073 | 0 | null | After poking around a lot I managed to hide this extra column just by setting negative margin in a few places. It's quite hacky but it works:
```
<Style TargetType="{x:Type ListViewItem}">
<Setter Property="Margin" Value="0,0,-7,1"/>
</Style>
<Style TargetType="{x:Type GridViewColumnHeader}">
<Setter Property="Margin" Value="0,0,-2,0"/>
</Style>
```
And perhaps add
```
<Trigger Property="Role" Value="Padding">
<Setter Property="Visibility" Value="Collapsed"/>
</Trigger>
```
in the GridViewColumnHeader style, as well.
First one can be set as negative as you like, it seems; it caps when it can't reduce anymore. Doing so will still leave a wee 2px gap on the right side of the headers, which the 2nd Style fixes.
Alas, the -2 margin applies to all GridViewColumnHeaders (and the Style Trigger method doesn't seem to work), so it can mess with inner borders and content alignment a bit, but if that's tolerable this works fine.
EDIT: Actually yeah scratch the -2 margin, it has too many negative side effects.
Inside `<Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}" TargetType="{x:Type ScrollViewer}">` you'll find a `<GridViewHeaderRowPresenter>`; set its Margin equal to `"0,0,-2,0"` and you'll get the same effect without the drawbacks.

You can see this by printing the values of `result` before rounding.
```
let result;
result = 2.4999999999999998;
console.log(result, Math.round(result));
result = 2.4999999999999997;

```
const withEight = 2.4999999999999998;
console.log(2.4999999999999998 === 2.5)
```
So `Math.round(2.4999999999999998)` is the same as `Math.round(2.5)`.
And, as [the specification requires](https://tc39.es/ecma262/multipage/numbers-and-dates.html#sec-math.round) that, when a number is rounded that is exactly between two integers, the higher integer is preferred.
>
1. Return the integral Number closest to n, preferring the Number closer to +∞ in the case of a tie.
So 3 is the result.

After changing the URN, the `APS_MODEL_VIEW` must be changed together since the GUID specified in the [config.js](https://github.com/autodesk-platform-services/aps-iot-extensions-demo/blob/master/public/config.js#L2) is the master view's GUID.

```
mybatis.mapper-locations=classpath:mappers/*.xml
```
If you're using `application.yml` instead of `.properties`:
```
mybatis:
mapper-locations: "classpath:mappers/*.xml"
```

As [double-beep](https://stackoverflow.com/users/10607772/double-beep) has mentioned [previously](https://stackoverflow.com/a/74958708) you need to:
> by adding `// @unwrap` to the headers
and leave it empty.
```
// @unwrap
```
Then call your modal like this:
```
/* global Swal */

```

As for the accuracy, you can first play around with your arguments and change the weights type or the number of neighbours. You can also try other techniques, I generally prefer to use svm. Also, not every data is predictable, so you might also be interested in checking that for your data by running a chi-squared analysis or other [feature selection techniques](https://towardsdatascience.com/how-to-find-the-best-predictors-for-ml-algorithms-4b28a71a8a80)

74,948,347 | 2 | null | 16,235,706 | 0 | null | One should not configure the `goto_definition` shortcut -- you would also need a shortcut to go back(and forth) after you jump to the definition.
Hence, consider configuring shortcuts: `goto_definition`, `jump_back`, and `jump_forward` as follows in your config file :
```
// go to the definition
{ "keys": ["ctrl+i"], "command": "goto_definition" },
// go back to the previous location
{ "keys": ["ctrl+h"], "command": "jump_back" },
// go to the next location
{ "keys": ["ctrl+l"], "command": "jump_forward" },
```
I find these three commands especially useful while trying to read code quickly.

> In JSX expressions that contain both an opening tag and a closing tag,
the content between those tags is passed as a special prop [React Documentation](https://reactjs.org/docs/jsx-in-depth.html#children-in-jsx).
And to use these special props you have to use `{props.children}`.
In your example, you have passed the content b/w opening and closing tag of a custom component but forgot to use it.
In projectTemplate component use the children that you have passed while invoking the component, like this:
```
<div className="projects">
{props.childrenanme}

74,948,673 | 2 | null | 74,944,999 | 1 | null | Could it be a property of the chosen projection? You can see it happening when adding the transformation by inspecting the `ax._position`, `ax._originalPosition` attributes:
```
Bbox([[0.015576512213622107, 0.0], [0.9844234877863779, 1.0]])
Bbox([[0.0, 0.0], [1.0, 1.0]])
```
You can add `ax.set_adjustable('datalim')` to make it change the limits, instead of the box (of the axes) to fill the given extent. Note how this slightly changes the `ax.get_xlim()` & `ax.get_ylim()`, so make sure that's acceptable for your application.
I personally often explicitly add the dpi and bbox when saving, to make sure the output has the intended dimensions, see the example below.
When I use a different projection, I can get it to work straightaway, the code below produces a clean 500x500px image with only the axes visible in the output, not the red figure. So perhaps it's a property of the PlateCarree projection?
```
map_proj = ccrs.Mercator()
fig, ax = plt.subplots(
figsize=(5, 5), dpi=100, facecolor="r",
subplot_kw={'projection': map_proj},
)
fig.subplots_adjust(left=0.0, bottom=0.0, right=1.0, top=1.0)
ax.set_extent([-10000000, 10000000, -10000000, 10000000], crs=map_proj)
ax.coastlines()
fig.savefig('Test.png', bbox_inches=0, dpi=100)

have an explicit annotation. To enable it, you can set
“`python.analysis.inlayHints.functionReturnTypes`”: true to your user

Where for "All Screen-Home", you're [manually logging](https://firebase.google.com/docs/analytics/screenviews#manually_track_screens) it in your app.
On the other hand, you will get a (not set) value in screen reporting if you are passing the screen name when the activity/fragment is not in a proper state or when you try to set the screen name before an Activity is presented. As such, (not set) is a placeholder that Google Analytics uses when it matches this scenario.

74,952,050 | 2 | null | 74,945,922 | 0 | null | The surprising behavior is not really related to `Math.round()`. The rounding happens already at the point of parsing the numeric literal, and you can see it by echoing the numbers directly without any explicit rounding:
```
> 2.4999999999999998
2.5
> 2.4999999999999997
2.4999999999999996
```
So the first number is immediately rounded up and the second down - but not corresponding to the common rules of decimal rounding (e.g. the second number still have the same number of digits).
The reason is that the numeric literal is converted to a 64-bit floating point number. This has a precision of 53 binary digits. The input number is therefore rounded to the closest number which can be represented with 53 binary digits.
The binary representation of 2.4999999999999996 is:
```
10.011111111111111111111111111111111111111111111111111
```
This is 53 significant binary digits, and the next higher binary number is therefore:
```
10.100000000000000000000000000000000000000000000000000
```
Which is 2.5 in decimal.
So numbers between 2.4999999999999996 and 2.5 cannot be represented exactly and have to be rounded up or down to fit in the floating-point format. So 2.4999999999999997 is rounded down to 2.4999999999999996 and 2.4999999999999998 is rounded up to 2.5.
(There is a special rule because 2.4999999999999998 is halfway between the two valid values. In this case the value is rounded towards the even significand.)
Math.round() on the other hand follows decimal rounding rules, which means we round up on 0.5 and higher. The result of the Math.round() operation is then straightforward: 2.5 is rounded up to 3 and 2.4999999999999996 is rounded down to 2.

1. Update N to be twice it was on the previous iteration

74,952,856 | 2 | null | 74,952,341 | 0 | null | When I modified your code by adding two lines to `print(len(x1), len(f1))` and `print(len(x2), len(f2))`, I got these results:

length of x2 and f2: 50 50

length of x1 and f1: 25 25

length of x1 and f1: 12 12
length of x2 and f2: 6 6
length of x1 and f1: 6 6
length of x2 and f2: 3 3
length of x1 and f1: 3 3
length of x2 and f2: 1 1
length of x1 and f1: 1 1
length of x2 and f2: 0 0
```
as you can see the length decreases each loop because `N` decreases and ends with an empty list `length of x2 and f2: 0 0` and this causes the error you have had. To fix the issue of 'the empty list' I suggest that you duplicate N; this means using `N*2` instead of `N/2`.

74,953,329 | 2 | null | 73,660,275 | 0 | null | Maybe it is too late to answer the question. It seems that because you have a list of `Form` component and `formRef` is connected to each form, logically the reference value of the forms are replaced one by one in the `formRef` till it gets to the last one. If you want to prevent that you can initialize `formRef` as an empty array like this:
```
const formRef = useRef([]);
```
And define `ref` prop of the `Form` component like so:
```
ref={el => {
if (el) formRef.current[index] = el
}}
```
finally change `submitFunction` :
```
const submitFunction = (value) => {
formRef.current.map(form => {
form.validateFields().then((values) => {
console.log("Values:", values);
});
})
};

It was first explored by Dan Kagel, read [here](http://www.kegel.com/peer-nat.html). In this technique, both peers are generally
assumed to be behind two different NATs. Both peers must be connected to an
intermediate server called a Rendezvous/Signaling server; there are many well-known Rendezvous protocols and SIP (RFC 3261) is the most famous one. As they are
connected to the server, they get to know about each other’s public transport
addresses through it. The public transport addresses are allocated by the NATs
in front of them. The Hole Punching process in short:
[](https://i.stack.imgur.com/Sx88i.png)
1. Peer 1 and Peer 2 first discover their Public Transport Addresses using STUN Bind Request as described in RFC 8589.
2. Using a signaling/messaging mechanism, they exchange their Public Transport Addresses. SDP(Session Description Protocol)[16] may be used to complete this. The Public Transport Address of Peer 1 and Peer 2 will be assigned by NAT 1 and NAT 2 respectively.
3. Then both peers attempt to connect to each other using the received Public Transport addresses. With most NATs, the first message will be dropped by the NAT except for Full Cone NAT. But the subsequent packets will penetrate the NAT successfully as by this time the NAT will have a mapping.
NAT can be of any type. If the NAT is, let's say, RFC 8489, Hole Punching won’t be possible. Because only an external host that receives a packet from an internal host can send a packet back. If this is the case, then the only possible way is .

74,955,736 | 2 | null | 74,955,413 | 2 | null | You just need to change the maximum threshold of the `LinRange` to be fitted to the maximum value of bars (which is 1 in this case), and change the input data for plotting to be the proportion of each segment:
```
my_range = LinRange(0, 1, 11)
foo = @. measles + mumps + chickenPox
groupedbar(
[measles./foo mumps./foo chickenPox./foo],
bar_position = :stack,
bar_width=0.7,
xticks=(1:2, ["A", "B"]),
yticks=(my_range, 0:10:100),
label=["measles" "mumps" "chickenPox"],
legend=:outerright
)
```
[](https://i.stack.imgur.com/5yijV.png)
If you want to have the percentages on each segment, then you can use the following function:
```
function percentages_on_segments(data)
first_phase = permutedims(data)[end:-1:1, :]
a = [0 0;first_phase]
b = accumulate(+, 0.5*(a[1:end-1, :] + a[2:end, :]), dims=1)
c = vec(b)
annotate!(
repeat(1:size(data, 1), inner=size(data, 2)),
c,
["$(round(100*item, digits=1))%" for item=vec(first_phase)],
:white
)
end
percentages_on_segments([measles./foo mumps./foo chickenPox./foo])
```
Note that `[measles./foo mumps./foo chickenPox./foo]` is the same data that I passed to the `groupedbar` function:

74,955,942 | 2 | null | 19,214,914 | 2 | null | The problem is that the plot panel does not have defined dimensions until drawing ("NULL unit"), but your legend guide . See also [npc coordinates of geom_point in ggplot2](https://stackoverflow.com/questions/60803424/npc-coordinates-of-geom-point-in-ggplot2) or [figuring out panel size given dimensions for the final plot in ggsave (to show count for geom_dotplot)](https://stackoverflow.com/questions/71250264/figuring-out-panel-size-given-dimensions-for-the-final-plot-in-ggsave-to-show-c). I think it will be extremely tricky to draw the legend guide in the exact same size as your panel.
However, you can make use of a trick when dealing with complex legend formatting: . The challenge here is to adjust the fill scale to perfectly match the range of your plot (which is not usually exactly the range of your data values). The rest is just a bit of R semantics. Some important comments in the code.
```
library(ggplot2)
corrs <- structure(list(Var1 = structure(c(1L, 2L, 3L, 1L, 2L, 3L, 1L, 2L, 3L), levels = c("Var1", "Var2", "Var3"), class = "factor"), Var2 = structure(c(1L, 1L, 1L, 2L, 2L, 2L, 3L, 3L, 3L), levels = c("Var1", "Var2", "Var3"), class = "factor"), value = c(1, -0.11814395012334, -0.91732952510938, -0.969618394505233, 1, -0.00122085912153125, -0.191116513684392, -0.0373711776919663, 1)), class = "data.frame", row.names = c(NA, -9L))
## to set the scale properly, you will need to set limits and breaks,
## I am doing this semi-automatically
range_fill <- range(corrs$value)
lim_fill <- c(floor(range_fill[1]), ceiling(range_fill[2]))
## len = 5 and round to 2 is hard coded, depending on the scale breaks that you want
breaks_fill <- round(seq(lim_fill[1], lim_fill[2], len = 5), 2)
## need to rescale the fill to the range of you y values,
## so that your fill scale correctly corresponds to the range of your y
## however, the actual range of your plot depends if you're in a discrete or continuous range.
## here in a discrete range
lim_y <- range(as.integer(corrs$Var2))
lim_x <- range(as.integer(corrs$Var1))
lim_vals <- lim_y + c(-.5, .5)
## actual rescaling happens here
new_y <- scales::rescale(breaks_fill, lim_vals)
## the position and width of the color bar are defined with
scl_x <- lim_x[2] + .7 # the constant is hard coded
scl_xend <- scl_x + .2 # also hard coded
## make a data frame for the segments to be created
## using approx so that we have many little segments
approx_fill <- approx(new_y, breaks_fill, n = 1000)
df_seg <- data.frame(y = approx_fill$x, color = approx_fill$y)
## data frame for labels, xend position being hard coded
df_lab <- data.frame(y = new_y, x = scl_xend + .1, label = breaks_fill)
## data frame for separators
sep_len <- .05
df_sep <- data.frame(
y = new_y, yend = new_y,
x = rep(c(scl_x, scl_xend - sep_len), each = 5),
xend = rep(c(scl_x + sep_len, scl_xend), each = 5)
)
ggplot(corrs) +
geom_tile(aes(x = Var1, y = Var2, fill = value)) +
geom_segment(
data = df_seg,
aes(x = scl_x, xend = scl_xend, y = y, yend = y, color = color)
) +
## now the labels, the size being hard coded
geom_text(data = df_lab, aes(x, y, label = label), size = 9 * 5 / 14) +
## now make the white little separators
geom_segment(
data = df_sep, aes(x = x, xend = xend, y = y, yend = yend),
color = "white"
) +
## set both color and fill scales exactly
scale_fill_continuous(limits = lim_fill, breaks = breaks_fill) +
scale_color_continuous(limits = lim_fill, breaks = breaks_fill) +
## turn off coordinate clipping and limit panel to data area)
coord_cartesian(xlim = lim_x, ylim = lim_y, clip = "off") +
## last but not least remove the other legends and add a bit of margin
theme(
legend.position = "none",
plot.margin = margin(r = 1, unit = "in")
)

74,956,186 | 2 | null | 19,214,914 | 5 | null | The following option is a function that can be added to a ggplot to take the plot and make the colorbar the same height as the panel.
Essentially it uses the same technique as Baptiste, but is a bit more robust to changes in the ggplot implementation, and moves the legend title to a more natural position, allowing neater alignment. It also allows more recognisable ggplot-style syntax.
```
make_fullsize <- function() structure("", class = "fullsizebar")
ggplot_add.fullsizebar <- function(obj, g, name = "fullsizebar") {
h <- ggplotGrob(g)$heights
panel <- which(grid::unitType(h) == "null")
panel_height <- unit(1, "npc") - sum(h[-panel])
g +
guides(fill = guide_colorbar(barheight = panel_height,
title.position = "right")) +
theme(legend.title = element_text(angle = -90, hjust = 0.5))
}
```
You can then do:
```
ggplot(corrs, aes(x = Var1, y = Var2, fill = value)) +
geom_tile() +
coord_cartesian(expand = FALSE) +
make_fullsize()
```
[](https://i.stack.imgur.com/SnrWa.png)
The drawback is that the plot needs re-drawn if the plotting window is resized after the plot is drawn. This is a bit of a pain, but it's a fairly quick-and-simple fix. It will still work well with ggsave.
Note that the color bar is the same height as the , which is why it looks a bit neater to turn the expansion off in `coord_cartesian`, so it matches the actual tiles of the heatmap.
Another example for one of the linked duplicates:
```
library(reshape2)
dat <- iris[,1:4]
cor <- melt(cor(dat, use="p"))
ggplot(data=cor, aes(x=Var1, y=Var2, fill=value)) +
geom_tile() +
labs(x = "", y = "") +
scale_fill_gradient2(limits=c(-1, 1)) +
coord_cartesian(expand = FALSE) +
make_fullsize()

If you need to get images delivered correctly you need to upload them to any web server and use a link to web server with such image. But that is not ideal too, Outlook also may block external images by default. The best solution is to embed images by attaching them to the mail item and then referring to them from the message body by using the CID attribute.
In Outlook you need to set the `PR_ATTACH_CONTENT_ID` MAPI property (the DASL name is "http://schemas.microsoft.com/mapi/proptag/0x3712001F") by using the `Attachment.PropertyAccessor.SetProperty` method. Then you can refer such attachments using the `src` attribute which matches the value of `PR_ATTACH_CONTENT_ID` set on the attachment. The `PR_ATTACH_CONTENT_ID` property corresponds to the `Content-ID` MIME header when the message is sent.
```
attachment = MailItem.Attachments.Add("c:\test\Picture.jpg")
attachment.PropertyAccessor.SetProperty("http://schemas.microsoft.com/mapi/proptag/0x3712001F", "YourId")
MailItem.HTMLBody = "<html><body>Your image embedded is <img src=""cid:YourId""></body></html>"

74,957,026 | 2 | null | 74,956,119 | 1 | null | In django, form classes are provided to make this easier.
What you want is to create a form class with a ChoiceField.
You can grab the data in this form rather than the views.py and then create a tuple the choices available from your dataset. We will do this by overriding the form's __init__ field so that load a dynamic set of choices instead of static set of choices.
Example:
```
from django import forms
from yourapp.models import Brand
class BrandForm(forms.Form):
def __init__(self, *args, **kwargs):
super(BrandForm, self).__init__(*args, **kwargs)
brands = Brand.objects.all()
brand_choices = tuple(i, brand.brand_name for i, brand in enumerate(brands))
self.fields['brand'] = forms.ChoiceField(choices=brand_choices)
```
Now in views.py you need to initialize the form and pass it into the context when you call `render()`
Then just put `{{ form }}` inside your html form to load all the fields into your form
(if you didnt pass your form into the context as 'form' you will need to change the reference inside of `{{ }}`)
P.s. With a static set of choices, you can define the tuple outside of the class and define the class like this (without needing to override __init__):
```
class BrandForm(forms.Form):
brand = forms.ChoiceField(choices=choices)
```

74,957,990 | 2 | null | 73,709,081 | 1 | null | Had a similar problem (not sure if it's your case but maybe it'll help someone reading this).
I had to clear the pycache folder(s) and re-discover the tests (the reload/refresh button at the top).
Had to do that for each test folder but it all works now.

74,958,060 | 2 | null | 74,957,982 | 1 | null | The help page for `plot.performance` mentions that the axis is an exception for modifying the graphical parameter. It then suggests that you can increase/decrease the size of the axis tick labels with
```
par(cex.axis=2)
```
If you also want to increase the thickness of the axes (the box that is shown around the plot, then use
```
box(lwd=2)
```
You can change 2 to a larger number if desired. Your commands would then be:
```
library(ROCR)
...
opar <- par(cex.axis=2)
plot(perf.tpr.fpr.rocr, colorize = T, main = paste("AUC:", ([email protected])),
lwd=4,
cex.lab=3,
cex.main = 3,
cex.sub = 3)
abline(a=0, b=1)
box(lwd=2)
par(opar)
```

74,958,708 | 2 | null | 74,946,942 | 1 | null | Notice these lines of code from [the lib's source on GitHub](https://github.com/sweetalert2/sweetalert2/blob/91147e9c2f67c3e4195f573619d82fec944c54e7/rollup.config.js#L14-L16):

if (typeof this !== 'undefined' && this.Sweetalert2) {
this.swal = this.sweetAlert = this.Swal = this.SweetAlert = this.Sweetalert2
}
```
There are two solutions:
1. Use Sweetalert2 which is exposed by the JavaScript file in any case.
2. Enable sandbox mode by adding // @unwrap to the headers. While the loader injects the script into the page, the script lives in the sandbox, which is disabled if @grant is none. With // @unwrap, you can achieve the desired this behaviour and use any of the exposed swal, sweetAlert, Swal, SweetAlert names.
