Selection of a chart caption as a filter

Hi guys,

I'm trying to handle the event when a user selects a value of a chart's label and pass that multiple value selection to my DS as filters.

So in my example I have a Heat Map and I want to be able to read if a user clics on the blue box that reprsents all values between 80 and 160.

The problem is that with CHART.getSelectedMember I only get the first selected value.

Any ideas ?

In this case I would expect an Array with all the Y axis values where there is a blue box {1,2,4,5,7,8,10,11,12}

Thanks !
