Pie chart not displaying refreshed values in dashboards 4.1

Hi All,

I have requirement to show data in combo box and Pie chart. when user clicks on the value in combo box the pie chart has to change and display according to value in combo box.

I used LO to get data into dashboards and data is getting from webi to LO. Here I have few doubts in linking between combo box and pie chart.

Combo box has values "cal month /year ( MAY 2015)"

Here my doubt is Combo box “destination” is single cell(which contains Calmonth/year) and I can’t give it as a source to pie chart, I tried to map the destination cell of combo box to pie chart values that also didn't worked out.

My pie chart is not displaying data according to the combo box value.

Please let me know how to connect combo box and pie chart so as to work dynamically( means if I click value in combo box pie chart has to change)

Please help in getting the data to pie chart

Thanks,
