I'm sorry if this has been asked/answered before, but I couldn't find it in my searches.
I'm working on building a dashboard of information, and I want some of my charts to show the past 6 months (or 12 months) of data automatically. Is there any way to create a filter for the chart to do this?
So for example, in this chart I would want to show Jan 15 - Jun 15. However, the green line is a 3 month average using the Previous() function, so I can't simply add a filter (also, then I would have to change the filter each month for the end user).
My other (somewhat related question) - Is there a way to use Max/Min or First/Last with custom sorted lists? I created the Month-Year detail myself, so when I do Max() or Last() I get SEP 14 instead of JUN 15. I was thinking that would be a way for me to look at the last x months by getting the maximum of Month-Year. I need to use some sort of calculation to summarize it to Month-Year because this is a summarization of multiple timestamps.
Let me know if anything doesn't make sense. I appreciate your help!
