Make a chart pie "selected"

Hi all,

I have a FPM Application that shows a list of customers (UIBB LIST) and a pie with the status of their sales order (UIBB CHART) splitted by status.

At FPM_START event, I would like to show the whole list of customer and the whole list of sales order, like if "All customers" were selected.

I can extract from my backend all data I need, but I don't know how to show the slices of pie all selected. By default, the slices of pie are all deselected.

Any help?

Thank you,

Francesca
