Color Each Bar Differently

As the Chart assigns one color to one series by default, you need to create a separate series for each bar to color bars differently. For this, employ a series template. Choose a data field and assign it to the seriesTemplate | nameField property. Each different value from this data field generates a separate series. In this demo, all values from the "age" data field are different, therefore, a separate series is generated for each, and all series are colored differently.
