I have a project that need to draw a fast chart with many series.
I must change start position of drawing to a favor position when user want.
.Net Chart is slow in lots of series.
I wanted to use this library:

but loading speed is too slow when count of series increases.
When I plot the chart, I must invalidate the chart for updates, drawing speed will be too slow if there are too many series.
I need at least 900 series in a chart for this project.

I wanted to use multiple layer series to decrease invalidate rate with the idea:

I do not know this idea would be helpful.

I tested LightningChart control but it could not help me.
