JavaScript/jQuery Chart - 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() {
$("#chartContainer").dxChart({
// ...
commonAnnotationSettings: {
tooltipEnabled: false
}
});
});Angular
<dx-chart ... >
<dx-common-annotation-settings
[tooltipEnabled]="false">
</dx-common-annotation-settings>
</dx-chart>

axis
Specifies the name of the value axis on which the value is specified. Useful for a multi-axis 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
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. The Chart evaluates the markup. Make sure that it does not contain malicious code. Refer to the following help topic for more information: Potentially Vulnerable API - customizeTooltip. 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.
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 chart 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:
dataSource: [
{ arg: "A", val1: 5, val2: 5.5 },
{ arg: "B", val1: 3, val2: 6.5 },
{ arg: "C", val1: 3.5, val2: 4.5 }
],
series: [
{ valueField: "val1", name: "Series 1" },
{ valueField: "val2", name: "Series 2" }
],
annotations: [{
type: "text",
text: "Text annotation",
argument: "B"
}]
To anchor the annotation to one of these series points, specify the annotation's series. For instance, the following code anchors the annotation to the point of Series 1:
annotations: [{
type: "text",
text: "Text annotation",
argument: "B",
series: "Series 1"
}]
See Also
template
Specifies a custom template for the annotation. Applies only if the type is "custom".
Template content must be presented as SVG elements.
We recommend that you do not use the foreignObject element to define template content (Safari does not support this element).
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.
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.
type
Specifies whether the annotation displays text, an image, or a template. This is a required setting.
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.
x
Used with y to position the annotation's center at a specific pixel coordinate. (0, 0) is the upper left corner of the UI component.
y
Used with x to position the annotation's center at a specific pixel coordinate. (0, 0) is the upper left corner of the UI component.
