I would like the possibility to change the color of a line depending on the value.

For example:

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.

Currently, you can customize the fill and stroke of the data point visuals using the DefaultVisualStyle property of the series. In the common scenario, you can use data bindings to data bind the fill and stroke of the corresponding element. Additionally, you can use the DefaultVisualStyleSelector for such customization. However, when the Direct2DRenderOptions or BitmapRenderOptions are used, data bindings and the DefaultVisualStyleSelector are not support. The bindings in the DefaultVisualStyle throw errors and the selector is not applied.

Add support for conditional styling. This should include support for data binding in the fill and stroke properties of the element from the DefaultVisualStyle, or support for DefaultVisualStyleSelector, or another type of API.

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. 

Edit:

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)
        {
            ViewModelBase.InvokeOnUIThread(() =>
            {
                for (int i = 0; i < Items.Count; i++)
                {
                    Items[i].X += (_random.NextDouble() - 0.5) * 0.1;
                    Items[i].Y += (_random.NextDouble() - 0.5) * 0.1;
                }
            });
        }

Currently, you can format the axis labels using the LabelFormat property. This allows the same format to display different label value for the different cultures when the UI culture is changed. 

Add support also for the Language framework property in this case.
