Why is the graph configured in the dashboard portlet not displaying results on drill down?

This issue can occur if the filters are not selected properly. Check for the filters chosen. Filters in the dashboard portlet must be selected in such a way that it can accommodate optimal data. As these are fusion graphs, we cannot increase the capacity of these graphs to accommodate 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.
