Color Each Bar Differently

The Chart assigns one color to one series. To color bars differently, create a separate series for each bar.

Assign the age field to the argumentField property of the commonSeriesSettings object to specify a common argument for the series. Then specify the valueField property.

Choose a data field and assign it to the seriesTemplate.nameField property. Each value from this data field generates a separate series.

To learn more about this type of data binding, refer to the following demo: Dynamic Series from the DataSource.

Backend API
$(() => { $('#chart').dxChart({ dataSource, palette: 'soft', title: { text: 'Age Breakdown of Facebook Users in the U.S.', subtitle: 'as of January 2017', }, commonSeriesSettings: { type: 'bar', valueField: 'number', argumentField: 'age', ignoreEmptyPoints: true, }, seriesTemplate: { nameField: 'age', }, }); });
