On occasion, Swift Charts draws a large pink rectangle over the entire chart area as shown in the screen shot below.
I have never been able to reproduce this issue consistently, so I do not know if it is an issue with the data I input into the chart, or an Apple bug. It happens only rarely, for one redraw cycle, then the chart returns to the correct display.
Has anyone experienced this issue, and if so, what was the source of the problem and how did you resolve it?
Apologies, this isn't really that helpful but I've never seen this issue and I do a lot of developing with Swift Chart on WatchOS 9, 10 and 11.
The only vaguely similar thing I've seen before was an issue when trying to render a SwiftUI chart as an image when it had the .chartXSelection API set for interaction.
Otherwise, I'd just have a look if there's anything else fairly unique you're doing with the chart. Maybe posting some of it's code could help.
