PolarLineSeries ItemsSource binding is not working when setup in code

I am extending the PolarChart, and attaching my items source property binding in code. This does not work. When I set the Items source directly the plot will load.

Here is the the basic code I am using :

      PolarSeries series = new PolarLineSeries()
        {
            SeriesBrush = trace.TraceColor,
            Title = trace.TraceTitle,
            IsClosed = false,
        };

        series.DataContext = trace;
        //series.ItemsSource = trace.DataSamples;
        series.SetBinding(LineSeries.ItemsSourceProperty, new Binding("DataSamples") { Source = trace });
        series.RhoBinding = new Binding(trace.YPath);
        series.ThetaBinding = new Binding(trace.XPath);

        Series.Add(series);

When I do the same type of code for a Chart and a line series the binding works fine. When I observe the ItemsSource property after the binding is established the value is null with the Polar chart code, whereas with the Chart code it has a value. I do no the thing I am binding to is not null as I can directly set the ItemsSource Property with it.

What is going wrong?

I found my problem. I was binding to LineSeries, when I should have used PolarSeries.

A few follow up questions about issues I'm having with the Polar Chart:

-I need to rotate where 0 degrees is on the theta scale. Can you add functionality to rotate the zero origin by X degrees?

-Major tick spacing seems to have no effect on Theta Axis. Really no settings on make on the axis objects seem to effect the chart.

-Is there a way to reverse the theta scale? Basically I want to go from 0 to 360 in the counter clockwise direction.

Hello

Thanks for these questions, I'll look into implementing these functionalities for you within the next 2 days.

Hello

In the next nightly build there will be StartAngle and IsReversed properties on the ThetaAxis. The issues with setting axis properties will also be resolved.
