Table Column - Day from Calendar. For each of past 30 days from the Reporting day, a column will be created in the visualization. Date format MM/DD
Used a Pivot table
Any aggregate should work, this assumes you have data points for each day in the 30 day window
I have taken column as date and trying to restrict 30 days accumulation value in pivot. But some null values are coming in the chart. can you give any suggestion on the same chart.
