I was testing my charts on a simulator and when I naved away and then back to the chart screen the Simulator’s chart was totally black screen; I could move the mouse over the points and the popouts would occur; and your license notice showed in the center of the chart. So it was almost like it thought all the drawing for the chart itself needed to be black on black.
It was always broken on the 2nd or later chart. Restarting the app fixed it. I tried removing all custom settings, and calling the invalidate; and nothing caused it to redraw correctly… Fortunately, when deploying to real devices everything worked correctly. Is this an expected side effect of testing on a simulator, or is their something that I can do to force a hard refresh of the chart…
FYI: The additional debug diagnostics don’t seem to do anything on a simulator, or at least I couldn’t find anywhere it was logged.
