I would like the possibility to change the color of a line depending on the value.
I have values between -1 to 10.
If the value is -1 I would like the color (or possible the opacity) to change until it goes back to 0 or above.
Issue1) When no RenderTransformOrigin is set to ScaleAnimation, all slices should be scaled from the pie chart center point. Currently thiss is not true, to better reproduce it , set MaxScale > 1 and notice slices overlap each other at the end of the animation.
Issue2) When RenderTransformOrigin is set to , for example (0, 0), all slices should start animating from topleft corner of the chart. Currently only the first one is animated from top left and all others are animated from pie chart center.
An InvalidCastException is thrown in the Fill/Background property binding in the series' DefaultVisualStyle when the RenderOptions is set to Bitmap or Direct2D.
Make the StepLineSeries being able to plot a 'step' for a single point. Currently the StepLine series does not support drawing a single data point when it is in the beginning or the end of the ItemsSource.
It appears the ChartView is also affected by the same SharpDX issue that affected the RadWebCam when it is used over Remote Desktop.
A simple test of any series will replicate the issue. If it is being used via Remote Desktop, the series will not render.
" Collection was modified; enumeration operation may not execute.'" - The exception is observed when the CLR exceptions are enabled from Visual Studio.
The Ellapsed event handler of the Timer is executed in background thread but modifying chart data in a background thread is considered bad practice which is not supported by our component. This is the reason we are declining this bug report.
General solution is to schedule the data update to happen on the UI thread with Dispatcher. When in ViewModel, the following code can be used:private void OnTimerElapsed(object sender, ElapsedEventArgs e)

Add a mechanism that allows the chart to process only the data within the viewport. This should improve the memory footprint and the performance of the chart in scenarios with big number of data points.
