Change current Marker
posted

I'm using the XamDataChart to show some ScatterSeries data and would like to graphically indicate that the marker in a series is selected.  Essentially, if the user clicks on the marker (or otherwise selects it), I'd like to do something to either resize or color (maybe both) that marker while it is the selected data point.

I've tried something like so to change the fill color and it works:

 

xamDataChart1_seriesMouseLeftButtonUp(object sender, DataChartMouseButtonEventArgs e)

{

    Shape shape = e.OriginalSource as Shape;

    //  

    Color color = new Color();

    color = Color.FromArgb(255,255,0,0);

    shape.Fill = new SolidColorBrush(color);

}

 

And that will change the shape fill for the marker I click on to red.  But what about resizing the shape to maybe twice as big?  How can I do that?

Thanks,

Matt
