Hi,
why on first Plot Point the scale is destroyed on plot points?
On Load Vieweds Ticks and Limits are shown…
it works, but wrong view.
Maybe try to minimize this, and use toy data? Its hard to understand what you are after here that could be causing the problem, and we can’t run your code.
Thanks for your Reply.
It Works, i interpret the Message as Deprecated Future Warning like PHP.
