Graph lost Plots

[manuelhoedl]

Hi,

i've got a strange Behaviour with the WPF Graph.

If one Plot is out of the Maximum Range he deletes the Plot a beginn a new one.

I've made a Example that is like my real Application.

Hope someone can help me.

Nice Wishes

I was able to reproduce your issue and have created a task to fix this. In short, when chart data is drawn out of range, the Raster target ends up interpreting this as a "no data" condition and clears the render area.

As a workaround, you can change RenderMode to Vector; or you can use a custom data source that disables chart optimization, such as the collection below that derives from the data source used in the example:

    [DataTypeDescriptor( typeof( GraphDataCollectionDescriptor<> ) )]
    public class CustomChartCollection : ChartCollection<double> {
        public CustomChartCollection( ) : base( 100000 ) { }

        protected override void OnDataChanged( GraphCollectionChangedEventArgs e ) {
            base.OnDataChanged( new GraphCollectionChangedEventArgs( 0 ) );
        }
    }

Just wanted to let you know this issue (#451487) was fixed in the Measurement Studio 2015 release.
