Angular Charts - Bar Color Customization

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.
