Hello all!

I'm using TIA portal WinCC RT Professional V15.1. I need to make a trend with the Y axis from 3000 to 0, that is, with the beginning at 3000 and the end at 0 (see attachment). It's easy enough to do from 0 to 3000, but I need to invert the Y axis on f(t) trend view. I tried this: opened the properties of the y axis, in the parameter "Value range" set Start value = 3000, End value = 0, but got an error that the initial value should be less than the final. Switch inverting axis, too, not found. Maybe there is some way to solve it?
