Unable to display chart type as (Col series Stack) view

Hi, I am trying to create a chart view for my app but I am not able to add column series (stack) view with the free version of Appsheet, Do I need to take business plan or any other premium plan for that ?
I am not able to add more column in “Column series chart type”.
If anyone have solution for that please reply or else share any available portfolio so I can see the definition.
