React Chart - FullStackedLineSeries.label

Configures point labels.

Selector: Label

Type:

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.

alignment

Aligns point labels in relation to their points.

Type:

HorizontalAlignment

Default Value: 'center'

This property accepts the following values:

center
Displays labels in the center of the point.
left
Aligns the left corner of the label to the center of the point.
right
Aligns the right corner of the label to the center of the point.

NOTE

This property has no effect if the rotated property is enabled.

argumentFormat

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

Selector: ArgumentFormat

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:

Hexadecimal colors
RGB colors
RGBA colors
Predefined/cross-browser color names
Predefined SVG colors
Paint server address

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.

Selector: Border

Type:

Object

connector

Configures the label connectors.

Selector: Connector

Type:

Object

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.
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.
point	The Point object.
seriesName	The name of the series to which the point belongs.

NOTE

As an alternative to the function’s parameter you can use the this keyword.

displayFormat

Specifies the label's text.

Type:

String

Default Value: undefined

This property is ignored if labels are hidden.

Use the parameters of the label.customizeText function as placeholders in the displayFormat property value.

The example below illustrates how to customize label text for all series and individual series:

font

Specifies font properties for point labels.

Selector: Font

Type:

Object

format

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

Selector: Format

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.

rotationAngle

Rotates point labels.

Type:

Number

Default Value: 0

verticalOffset

Along with horizontalOffset, 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 up, a positive number shifts them down.

visible

Makes the point labels visible.

Type:

Boolean

Default Value: false
