Since the February update, we are having issue with the "Line and Stacked Column chart". Previously we were able to have all of these fields in the visual the the visual would work perfectly. Now the visual is completely blank.
The only way to "fix" this issue is to remove the field that we slotted into the either the "column series" or "column values field" which defeats the entire purpose of the graph we chose. If anyone has this issue and has some insight, please reach out. This is a vital report for our company. Thank you!
