Unexpected error occurred in Chart

Hi Guys

I am getting "Unexpected error occurred;Contact your system administrator" error in chart in design studio application.

Scenario: I have one query and one chart, one Cross tab. Am using Dimension filter for filtering the data. For some of the selection the chart is displaying the data properly. For some selection, i can able to see the data in cross tab. but the chart is throwing an error.

Please let me know if anyone have the solution for this.
