Hello

We have an issue with high rated live data on xamDataChart.
Planned usages supposed that will be shown at maximum 3 line series with some about 5-10 thousands points.
This data will be rewritten on 1 point per 2-3 ms (frequency of incoming data is 300-500 Hz).
Also this data may have in some cases lot of artifacts in data (smoothing of data is not possible).

Issue that exist now that the performance for it in full screen chart is poor.
In small size of chart it is an acceptable performance, but if chart is grown in size and data has a lot of noise in it, performance became not so good.

Sample include

Our sample is based on "Updating Data Points" sample from xamFeatureBrowser.

Series in xaml markup for version 12.1:

<ig:LineSeries
DataContext="{Binding Source={StaticResource DataSource1}}"
ItemsSource="{Binding Data}"
ValueMemberPath="Value1"
XAxis="{Binding ElementName=XAxis}"
YAxis="{Binding ElementName=YAxis}"
MarkerType="None"
UseLightweightMarkers="True"/>

Problem condition:
Window maximized.
Global artifact level - high.

Thanks for attention.
