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.
Hello Andrey,
Thank you for your post. I have been looking into it and I tested your sample and it seems like that everything works ok on my side. Although I can suggest you see this link from our online documentation:
http://help.infragistics.com/Help/NetAdvantage/WPFDV/2011.1/CLR4.0/html/xamDataChart_Chart_Performance.html
where it is described how to improve the performance of your XamDataChart.
Thank you for your reply. But I don't understand what you meant when you wrote that "everything works ok". Do you set the setting to the values that are described in my first post (Window maximized; Global artifact level - high)? With this settings UI works hardly. The data in the charts updates only every 2-3 times per second. Look in Task Manager for CPU usage.
