Error Dashboard: "Maximum limit is exceeded record. Reduce the number of records"

Hi.

In CRM2011, when I build a chart (Bar) to a dashboard from a table with more than 55,000 records I get the following error message: "Maximum limit is exceeded record. Reduce the number of records"

The FetchXML of chart is as follows. How I can fix this problem without affecting the performance.
