I have a .net maui solution where I use the cartesian chart control.

The charts underlying data is changed by user actions and the chart rerenders just fine.

My chart supports crosshair - when user touches a point in the chart, a crosshair is shown.

Now I need to hide the crosshair every time I change the underlying data but I can't figure out how to do this. It seems that once the crosshair is shown, it stays there even on underlying data refresh and I can't seem to make it disappear.

I did find an InvalidateCrosshair method on the Axis type but that one also takes a point that I don't know how to supply or if it is meant to function the way I want.

Anyone knows how to remove the crosshair on an existing chart control and then not show it until the next time the user taps the chart?
