dynamic bar chart

[Manel222]

Hello, I have this data set (attached), I need to display in a bar chart the number of participation per month, knowing that the months displayed must depend on the start date and end date variables chosen by the user and the number of participation for example for the month of June 2024 must display the cumulative number of all months until 06/30/2024, for the month of May, the cumulative number of participation until 05/31/2024 and so on

any idea please ?

Not sure I got 100% your question but I think this video might help: using variables to let the user choose what he/she wants to see in the charts.
Close to this Qlik recently launched Cyclic dimensions too, but in your case variables might be handy

Hope it helps

Cheers
