SfCartesianChart freezes UI when loading large amount of data

[Md. Shahadat Hossen Shakil]

When populating large amount of datapoint(i.e. 10000+), the SfCartesianChart freezes the UI for a bit.
We have tested four graphs with 10000 data point in the test project and it seems the UI freezes for roughly 2.5 seconds when loading the data. The behavior is same in release mode.
Is there any way we can increase the performance of the graphs?
A demo video and test project is attached.
Tested Platform: Windows
Processor: 11th Gen Intel(R) Core(TM) i5-1135G7
RAM: 16.0 GB
Tested OS version: Windows 11

Hi Shahadat,

When it comes to performance, we always suggest using fast series. As per our previous update, we have considered the feature request for a fast column series. In the meantime, you might want to try our fast line series to see if it suits your scenario.

<chart:SfCartesianChart.Series>

     <chart:FastLineSeries ItemsSource="{Binding DataCollection}"

                     XBindingPath="Time"

                     Fill="Red"

                     EnableTooltip="True"

                     YBindingPath="Value"/>

 </chart:SfCartesianChart.Series>

You can check performance with fast line series in this sample. dot_net_MAUI_Chart_Performance_Analysis
