[#5003] - invert/reverse charts

Hello

I am creating a line chart, which shows a ranking on the Y-axis and time on the X-axis. Since the best place on a ranking is 1, and the greater the rank is, the worse it is, I have to reverse the Y-axe of the line chart. (1 is at the very top, and e.g. 20 in my case is at the very bottom, crossing the X-axis.)

I asked in the Forums, but no one could tell me how to do it, so I assume this feature is not avaible yet. Correct me please if there is such a feature.

Thanks in advance.
