I ran this app on my IPhone 12 and screen shots like below:
Any helps will appreciate it.
Why Pie Chart View redraw lag after I switch schemes .system, .light & .dark mode?
It's impossible for anyone to answer your question if you don't include a reference to the source code of this app.
What is the problem ?
- what is the first screenshot ? When do you get it ?
- Is it the time it takes to redraw ? -> screen shots don't show for this of course
- is it you don't see any label or background color in light mode ? -> That's what appears in screen shots, but not the title of your post…
If the second, how did you define value labels colors ? If white, you get white on white… So, select label color in the attributes inspector.
And please be more precise in the question. And show code.
