Stacked bar chart without creating new column for each group

Hi all,

I want to build a chart, where I have a column in my data source which contains groups. This chart should be stacked with bars/columns colored by each group’s data (client in screenshot_1).

I can do it by making a separate column in data for each and every group and then using each column as a separate series for the chart (screenshot_2). But making new series for each column is not a feasible option for my current graph. Is there a way to do it easily with configs of highchart elements?! (something like in matplo

tlib/seaborn: hue=“group_col”)

Thanks in advance for your suggestions!
