jQuery Chart - series.label

Configures point labels.

Type:

Object

Declared in commonSeriesSettings, the label settings apply to all point labels in the chart. Declared in a series configuration object, the label settings apply only to the point labels that belong to this particular series. The series-specific label settings override the common ones.

    $("#chartContainer").dxChart({
        // ...

            label: {
                // Settings for all point labels of an individual series

alignment

Aligns point labels in relation to their points.

Type:

String

Default Value: 'center'
Accepted Values: 'center' | 'left' | 'right'

argumentFormat

Formats the point argument before it is displayed in the point label. To format the point value, use the format property.

Type:

Format

Default Value: undefined

A point label displays only the point value by default. Using the label.customizeText property, you can instruct the label to display the point argument as well. The argumentFormat property applies in this case only. This property accepts an object whose fields are described in the format section.

NOTE
DevExtreme UI components provide a wide choice of predefined formats. If you are, however, going to use custom formats, link the Globalize library to your project. Learn how to do this from topics in the Installation section.

backgroundColor

Colors the point labels' background. The default color is inherited from the points.

Type:

String

Default Value: undefined

This property supports the following colors:

You can remove the label's background by setting this property to "none". In this case, the label's text is the same color as the point.

border

Configures the borders of point labels.

Type:

Object

connector

Configures the label connectors.

A point label is always displayed near its series point, though the label is placed separately. To make the relationship between the series point and its label evident, use a connector.

By default, label connectors are hidden. To make them visible, set the connector.visible property to true.

customizeText

Customizes the text displayed by point labels.

Type:

Function

Function parameters:
pointInfo:

Object

Information on the series point.

Return Value:

String

The text for the label to display.

Cannot be used in themes.

This property accepts a function whose parameter exposes the following fields.

Field Description
originalValue The raw value of the point.
value The originalValue after type cast.
valueText The value with an applied format and converted to string.
originalArgument The raw argument of the point.
argument The originalArgument after type cast.
argumentText The argument with an applied format and converted to string.
size The size value of the point. For bubble series only.
index 0 - if the point is minimum; 1 - if the point is maximum. For range area and range bar series only.
point The Point object.
seriesName The name of the series to which the point belongs.

The following fields are inherent to stacked-like series only.

Field Description
percent The percentage value of the point.
percentText The percent with an applied format and converted to string.
total The sum of all values in the stack.
totalText The total with an applied format and converted to string.

The following fields are inherent to financial series (candlestick and stock) only.

Field Description
originalOpenValue The raw open value of the point.
openValue The originalOpenValue after type cast.
openValueText The openValue with an applied format and converted to string.
originalCloseValue The raw close value of the point.
closeValue The originalCloseValue after type cast.
closeValueText The closeValue with an applied format and converted to string.
originalHighValue The raw high value of the point.
highValue The originalHighValue after type cast.
highValueText The highValue with an applied format and converted to string.
originalLowValue The raw low value of the point.
lowValue The originalLowValue after type cast.
lowValueText The lowValue with an applied format and converted to string.

font

Specifies font properties for point labels.

Type:

Object

format

Formats the point value before it is displayed in the point label.

Type:

Format

Default Value: undefined

See the format section for information on accepted values.

If you specify the format with an object and apply it to a full-stacked-like series, this object can also contain the percentPrecision field. Full-stacked-like series points have absolute and percentage values. The percentPrecision field specifies how many decimal digits the percentage values should have:

JavaScript
format: {
    type: "fixedPoint", // the format of absolute values
    precision: 1, // the precision of absolute values (123.456 --> 123.4)
    percentPrecision: 2 // the precision of percentage values (12.3456 % --> 12.34 %)
}

horizontalOffset

Along with verticalOffset, shifts point labels from their initial positions.

Type:

Number

Default Value: 0

The number assigned to this property specifies the shift in pixels. A negative number shifts the point labels to the left, a positive number - to the right.

position

Specifies whether to display point labels inside or outside of series points. Applies only to bubble, range-like and bar-like series.

Type:

String

Default Value: 'outside'
Accepted Values: 'inside' | 'outside'

NOTE
The default value for full-stacked bar and stacked bar series is 'inside'.

rotationAngle

Rotates point labels.

Type:

Number

Default Value: 0

showForZeroValues

Specifies whether or not to show labels for points with zero value. Applies only to bar-like series.

Type:

Boolean

Default Value: true
This member is exposed by the following entities:

verticalOffset

Along with horizontalOffset, shifts point labels from their initial positions.

Type:

Number

Default Value: 0
