label

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.

Use the HorizontalAlignment enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Left, Center, and Right.

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

• Data Formatting - shows how to apply formatting to various widget elements.

This option supports the following colors:

• Hexadecimal colors
• RGB colors
• RGBA colors
• Predefined/cross-browser color names
• Predefined SVG colors

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

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 option to true.

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

• Data Formatting

This option accepts an object whose fields are described in the format section. However, there is one more field, called percentPrecision, which is available only to full-stacked-like series, where one point always has an absolute and a percentage value. The percentPrecision field specifies how many digits after the decimal point to save in the percentage value. See an example in the following code.

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 %)
}

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

Use the RelativePosition enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Inside and Outside.

The number assigned to this option specifies the shift in pixels. A negative number shifts the point labels up, a positive number shifts them down.
