Charts only sort one way. This is especially problematic when visualizing negative numbers on something like a stacked bar chart. Need to support both ASC and DESC in sorting. I thought it was supported before, but don't see it in Nov'16 release.
I have quite a few cases that would require the sorting in ascending order instead of the descending order. For example, when the bar chart shows the flight hours of aircraft under maintenance, the aircraft with "small" flight hours are problems to fix. Under current default bar chart sorting, my users have to scroll down every time to find the aircraft having the problem. So, it is a significant problem to my business users.
