I'll try to aks this question although I'm no native in English but I'll try to make myself as understandable as prossible.
I tried to to a comparison from year to year in percent. For Example: I have the Units ordered imported from 2012 - 2015 (YTD)
In my Window i Show someting like this:
If i choose 2015 I would like a comparison in percent of the YTD 2015 with 2014 the same timespan.
If I choose 2014 and April i would like to compare April 2014 with 2014 with Change in percent.
How can i code this that the comparison does work with the filters set?
