related to the question how to color the full chart vertically i have an other one:
The customer wants gaps in series also to be colored / highlighted and not just not shown. I wonder what’s the proper approach for this. PaletteProvider seems to be no solution since the values to be shown somehow are Double.NaNs. So are again annotations the best solution? Or is there any other way i’m not aware of?
Yes, this approach is the best one which I can think of for now. Also, there might be another way of achieving that using axis bands(refer to Digital Line Chart example), which we introduced in SciChart 2.0v, but there isn’t any way how to customize their drawing over inheritance/overrides.
I logged your request and we will consider providing a way to do this using axis bands in next version.
It sounds to me like a custom series is the only way to go for such a thing. It would require custom work. Is this something you or your clients are interested in?
Alternatively you could implement two series, one which contains just normal values and another which contains just error values.
Agreed that annotations are slower than main series, they are WPF UIElements, not drawn on bitmaps. This enables them to benefit from interactivity, templating, tooltips, mouse-hovers, datacontext binding but on the downside means we’re back to the slow WPF rendering engine!
