Can't programmatically binding to OxyPlot properties

I want to create a databinding programmatically for the LineSeries.Color property. The LineSeries.Color property must be a dependency property because you can bind to it in XAML. However, if I want to create a binding dynamically in code-behind, I need the static property LineSeries.ColorProperty. For example, the WPF TextBox.Text has an analogous TextBox.TextProperty. But Intellisense shows no LineSeries.ColorProperty.

See OxyPlot.Wpf.Series.ColorProperty. It is public and the type is System.Windows.Media.Color

thanks for your quick reply. I tried your solution and in order to get it to work we must use OxyPlot.Wpf.LineSeries (because it a DependencyObject and that is required for DataBinding). I used the following code:
            var ls = new OxyPlot.Wpf.LineSeries();
            var b = new Binding();
            b.Source = mySourceObject;
            b.Path = new PropertyPath("Color");           
            b.Mode = BindingMode.TwoWay;
            ls.SetBinding(OxyPlot.Wpf.Series.ColorProperty, b);

This code compiles perfectly but when I try to add the LineSeries to the model it won't compile:
           PlotModel model
           model.Series.Add(ls)
I get an error telling me that "ls" is the wrong type. It is expecting the non-WPF LineSeries. I have looked for a WPF version of PlotModel but can't find any. Thanks for you help.

No, you cannot add a OxyPlot.Wpf.LineSeries to the OxyPlot.PlotModel. Try adding the "ls" to the Series collection in your OxyPlot.Wpf.Plot control.
