JavaScript/jQuery RangeSelector - chart.series.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.

$(function() {
    $("#chartContainer").dxChart({
        // ...
        series: [{
            label: {
                // Settings for all point labels of an individual series
            }
        }, {

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

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 %)
}
