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.
As Andrew mentioned, there is some internal issue in the OpenGL implementation of the 2D/3D engine. Because OpenGL is deprecated and considered to be a quite low priority – all I can do for now – is create a bug in our bug tracker (https://abtsoftware.myjetbrains.com/youtrack/issue/SCIOS-966) so someone will pick it up and investigate/fix the issue.
We will keep you updated on the above issue progress and will let you know when it is fixed.
This issue is still happening using the latest v3 version ( pod ‘SciChart’, ‘3.1.0-nightly.5287’) for the iOS and we are very unhappy that the charts are black on simulators.
We are trying to produce screenshots for the Appstore using Fastlane automation in order to present nicely to our clients our new tools related to multiple charts and indicators panes and we cannot do it because of this issue.
Can you please suggest any quick fix or push your team to fix it ASAP ?
Thanks a lot for your support
