Hi Reemali,
Whenever you are trying to filter data on the basis of value selection in dropdown at the end of this microflow just take a change object & simply refresh tha data.
Still not working then make a nanoflow -> call your filder data microflow inside this nanoflow & in the nanoflow you can see refresh entity activity try to use this & call this nanoflow on the dropdown value selection.
Hi Reemali,
As you are already using a helper object, add the same object in the data source microflow for the piechart, then you can call a microflow or nanoflow on change of your reference selector and at the end of the flow use a change activity to refresh the helper object. This should trigger the data source microflow of piechart again.
Hope this helps!
Thanks
