Filter and Drilldown Question

Hello,

I have created a matrix and a donut chart. The Matrix has rows which are my organization structure, the columns are based on a categories showing all except for 1, which is shown separately in the donut chart.

When I click on the Matrix Rows (setup as a hierarchy), my donut chart does not show any information, but if I drilldown on the Matrix Row, data appears. If I add the category back to my Matrix then the donut chart works. I was wondering why would the donut chart not show any data?

Is there any work around to this? I would like to keep the category shown in the Donut Chart separate from the Matrix to highlight it.

Thank you,

Is there any work around? I would like to keep this one category from being included in the Matrix and to show it separately to highlight
