If there a way to bind series color/thickness to a custom control so the line color and thickness changes dynamically when user select a different color/thickness? I will need use this with the MVVM dataseries API.

Yes there is, you just have to bind RenderableSeries.SeriesColor and StrokeThickness to a property in the viewmodel.
e.g.
<s:SciChartSurface>
<s:SciChartSurface.RenderableSeries>
<s:FastLineRenderableSeries SeriesColor="{Binding Color}" StrokeThickness="{Binding StrokeThickness}"/>
</s:SciChartSurface.RenderableSeries>
</s:SciChartSurface>
Then in a viewmodel
public class MyViewModel : INotifyPropertyChanged
{
private int _strokeThickness = 1;
private Color _color = Color.FromArgb(0xFF, 0xFF, 0x66, 0x00);
public int StrokeThickness
{
get { return this._strokeThickness; }
set
{
this._strokeThickness = value;
OnPropertyChanged("StrokeThickness");
}
}
public Color Color
{
get { return this._color; }
set
{
this._color = value;
OnPropertyChanged("Color");
}
}
protected void OnPropertyChanged(string prop)
{
var handler = PropertyChanged;
if (handler != null)
{
handler(this, new PropertyChangedEventArgs(prop));
}
}
}
I hope this helps!

- Sorry Andrew, I think I asked the question too simplistically and thus the simplistic answer. I actually figure it out. Thanks.
