Feature Request:

I have 4 entities , one entity is a summary of the other 3.
Stacked Column Chart , Summary of entities . Tooltip to show all entities + summary .

Currently i use 3 columns, and for the Summary i use Line with "show Datalabel = true " . This has the problem that the tooltip are not shown for all entities , and the timeline for column and line is somehow not the same ( endtime)

I want to show the summary for each Day in the chart + the tooltip should show all 4 values . No need of a line entity - just i have not found a better way doing it.

Stacking the summary is no solution .

Describe the solution you'd like

If we could add a stacked column entity with following

• show in header = true , show in tooltip = true , show in chart = false , show datalabel on top of chart = true

This would solve a lot of "problems" . No need to Mix Column and Line .

Describe alternatives you've considered

I think JS could (partly ? ) solve this with the tooltip, but i have not managed to get this solved .
