LightningChart Support Forums

Hi
I have a chart inside wpf that I use None Bindable to draw values.
I also draw each value as a separate LineCollection.
The number of these quantities is large and may reach 30,000 or 40,000.
I did my test for about 100 of these values. Drawing these 100 numbers takes about 2-3 seconds.
I want to know if there is a way to draw a large number of LineCollection in NoneBindable mode and at very high speed? So that drawing 30,000 or 40,000 values takes less than 1-2 seconds?

thank you.

The most effective rendering will be with smallest amount of series (in this case LineCollection). Instead of multiple LineCollection, you should add all segments (SegmentLine) to array of line-segments (lineCollection.Lines property).
At leastm you should group same color and line-width segments into same LineCollection.
Note that if your value should be connected as continues line, it is more efficient to use 'standard' line series. Depending on distribution of x-values, you can use PointLineSeries, FreeformPointLineSeries, SampleDataSeries, or SampleDataBlockSeries.

Even 100 LineCollection should not take 3 seconds to render. Make sure that you using BeginUpdate() and EndUpdate() method calls, to initiate Chart (properties) update as a batch.
