I don’t see a Date column in your table?
But, a general approach to summarise data by date is as follows:
- Use a math column to convert the date to an integer in yyyymmdd format:
Year(Date)*10^4
+Month(Date)*10^2
+Day(Date)
- Create a multiple relation column that matches the math column with itself.
- Use a Rollup->Sum via the relation to sum the value/s that you’re interested in.
