A lot of points

[dgkorenje]

I use windows 11. Latest version of livecharts2.
If I have a lot of points on the chart (over 20000), only the hovering over it is consuming whole cpu core despite hidding tooltips. Even if the points are outside of visible range the cpu consumption doesn't decrease. What is causing this and how can I increase performance by disabling needless stuff?

Ok I think I'll make a system to add and remove points from the series, depending on the view. Or maybe have them downscaled in non-visible areas. Again I don't like this because points need to be sorted. Chart works smoothly with up to 5000 points which is not a lot. That processing when hovering with mouse over the chart needs to be addressed and how to eliminate cpu consumption especially if you don't need interactions with points.

ok removing and adding financialpoints is causing some issues. They are not removed from the chart and and stay where they are attached to nowhere. If I scroll back, the points are magically reattaching to the sequence.

This is how I remove and add points from the chart. cdef.ChartValues = all points, cdef.VisibleValues = points for the chart.

Here is the video of the problem:

If I leave points on the screen, the cpu consumption becomes intensive. If I let the points stack it becomes ok. I have no idea what's happening in the background but it's not good.

Ok I think I got it. You must set MetaData to nothing.

visibleValues.RemoveAt(i)
p.MetaData = Nothing
