I have attached packaged workbook for your reference.
I have created a Bar chart showing the number of records for each day selected via Parameters (Start_date, End_date)
I have difficulty in creating another Line chart which should calculate the average of "E2E overall" for each day selected via Parameters (Start_date, End_Date).
The average should be calculated for graph selected i.e 27-Feb to 26-Mar... For example, on 27-Feb, we can see 82 records. Therefore, it should calculate the average of 82 records of "E2E overall" i.e 4.616. Similarly for others dates in the range.
