Hi,

To customize the colors of legend data points in a stacked column chart , you can follow these steps: 

1. Add a new field in your data structure to store the color information for each series or data point. 

For example: 

LegendColor: This field will hold the hex color codes (e.g., #FF5733).

2.In the Chart DataPoint List, map your data source (Aggregate or Static Entity) and include the custom color field (LegendColor). 

3.Assigne these value in the chart.
