I'm trying to create a weekly date variable so that my graph has node at each week of the data set. Currently, I was able how to figure how to format the dates monthly. So for example, if I run the report for the dates 9/1/2015 - 11/5/2015, I receive the monthly nodes: 9/1/2015, 10/1/2015, and 11/1/2015.
Here's the definition I used for the monthly variable: =ToDate(FormatDate([Incident Reported Date Time];"Mmm YYYY"); "Mmm YYYY")
However, I'd like to have the results broken down by weeks, instead of months. I've tried = Week([Reported Date]), but this returns the weeks number, instead of the date. I'm unsure if I need to somehow format this result into a date string or try another approach.
Any assistance would be highly appreciative. Please let me know if I need to clarify anything.
