Angular PolarChart - commonAnnotationSettings
Settings specified here can be ignored in favor of individual annotation settings specified in the annotations[] array. Refer to the array's description for information on how to configure annotations.
The following code shows the commonAnnotationSettings declaration syntax:
jQuery
$(function() {
$("#polarChart").dxPolarChart({
// ...
commonAnnotationSettings: {
tooltipEnabled: false
}
});
});Angular
<dx-polar-chart ... >
<dx-common-annotation-settings
[tooltipEnabled]="false">
</dx-common-annotation-settings>
</dx-polar-chart>

color
This property supports the following colors:
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
- Paint server address
component
An alias for the template property specified in React. Accepts a custom component. Refer to Using a Custom Component for more information.
customizeTooltip
The annotation's configuration object.
This property should be assigned a function that returns an object with the following fields:
| Field name | Description |
|---|---|
text |
The tooltip's text. |
html |
The HTML markup displayed in a tooltip. To use external resources (for example, images) in the markup, specify the size of the area they occupy beforehand. |
color |
The tooltip's color. |
fontColor |
The color of the tooltip's text. |
borderColor |
The color of the tooltip's border. |
this keyword.See Also
image
Configures the image to be displayed in the annotation. Applies only if the type is "image".
To display an image, assign its URL to the url property and use the height and width properties to resize the image. Otherwise, assign the URL directly to the image property.
offsetX
The number assigned to this property specifies the shift in pixels. A negative number shifts the annotation to the left and a positive number shifts it to the right.
See Also
offsetY
The number assigned to this property specifies the shift in pixels. A negative number shifts the annotation up and a positive number shifts it down.
See Also
paddingLeftRight
Used with paddingTopBottom to generate an empty space around the annotation's text or image (specified in pixels).
paddingTopBottom
Along with paddingLeftRight, generates an empty space around the annotation's text or image; specified in pixels.
render
An alias for the template property specified in React. Accepts a rendering function. Refer to Using a Rendering Function for more information.
series
Anchors the annotation to a series point. Accepts the name of the point's series.
Use this property when the annotation is positioned relative to an argument.
For example, the following PolarChart fragment displays two series and an annotation. The annotation is positioned relative to the argument B but not anchored to any of the two series points that correspond to this argument. To anchor the annotation to a series point, specify the annotation's series property:
dataSource: [
{ arg: "A", val1: 21, val2: 10 },
{ arg: "B", val1: 26, val2: 11 },
{ arg: "C", val1: 14, val2: 5 }
],
series: [
{ valueField: "val1", name: "Series 1" },
{ valueField: "val2", name: "Series 2" }
],
annotations: [{
type: "text",
text: "Text annotation",
argument: "B",
// series: "Series 1"
}] 
See Also
text
Specifies the annotation's text. Applies only if the type is "text".
textOverflow
Specifies what to do with the annotation's text when it overflows the allocated space after applying wordWrap: hide, truncate it and display an ellipsis, or do nothing.
Use the VizTextOverflow enum to specify this property when the UI component is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Ellipsis, Hide, and None.
tooltipComponent
An alias for the tooltipTemplate property specified in React. Accepts a custom component. Refer to Using a Custom Component for more information.
tooltipEnabled
A tooltip is a miniature rectangle that appears when a user long-presses an annotation or hovers the mouse pointer over it.
The tooltip displays the contents of the description field or the text or markup returned from the customizeTooltip function. If the description is empty, and customizeTooltip returns nothing, the tooltip does not appear.
Tooltips for annotations and series points have the same appearance as specified in the tooltip object. You can use the annotation's customizeTooltip function to customize the annotation tooltip.
tooltipRender
An alias for the tooltipTemplate property specified in React. Accepts a rendering function. Refer to Using a Rendering Function for more information.
wordWrap
Specifies how to wrap the annotation's text if it does not fit into a single line.
The following modes are available:
"normal"
Text breaks only at allowed breakpoints (for example, a space between two words)."breakWord"
Words can be broken if there are no available breakpoints in the line."none"
Word wrap is disabled.
If the text overflows the container even after word wrap, the UI component applies the textOverflow property.
Use the VizWordWrap enum to specify this property when the UI component is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Normal, BreakWord, and None.
x
Used with y to position the annotation's center at a specific pixel coordinate. (0, 0) is the upper left corner of the chart.
