The graph configured in the dashboard portlet doesnot display results on drill down
Check for the filters chosen. Filters in the dashboard portlet must be selected in such a way that it can accomodate optimal data. As these are fusion graphs, we cannot increase the capacity of these graphs to accomodate more data as this being a limitation of fusion charts. Hence, select/modify filters such that lesser data is shown and avoid configuring data for YTD/SKU level filters
