How to use Report Acceleration in a Dashboard

I have a base report "Hourly Checkpoint Blocks" for a time span of 1 hour that I have accelerated for 1 month. I.E. index=checkpoint action=block | timechart count by action I have created a dashboard and added a New Panel from Reports and selected the "Hourly Checkpoint Blocks" report. The dashboard shows data for the report, only 1 hour. How do I use the report for a 30 day time span?
