Suggestion: I am displaying a plot which has multiple lines, for each line I display a legend. User can hide some of the lines but legend for that line is still visible - I need to recreate the Plot.Legend.ManualItems every time I do this and add/remove the affected lines from/to legend.

Plot.Legend.ManualItems.Add(new() {
   Label = "label1",
   IsVisible = true // add something like this - the default would be true
});

later in code

Plot.Legend.ManualItems[0].IsVisible = false;

Thanks for considering this,
Libor
