In a Swift Chart that listens for drag gestures in order to display a RuleMark with an annotation, the y-axis scale changes while dragging which causes the entire chart to jump. I have a small code example that demonstrates this at https://github.com/mvolkmann/ChartJump. See the two screenshots there.
I have the very same problem with the annotation using chartOverlay. Did you come up with a solution? I have been thinking about it for 2 days and I concluded nothing…
I came up with a simple solution consisting in just setting the Y (or X) axes scale manually in this way (added chartXScale also, as sometimes I have experienced the same issue also with X axis domain):
Chart {
// Chart implementation
}
.chartYScale(domain: 0...50)
.chartXScale(domain: 0...25)
In this way you can prevent the jump to happen.
Thank you SO MUCH @MTBff! That solves it for me!
Overriding the default overflow resolution fixes this:
.annotation(overflowResolution: .init(x: .fit(to: .chart)) { ... }
