Ive been using the toolkit and adding some great charts to our app.

I would like to be able to change the line color of an existing RTSimpleSingleValuePlot that is already displaying in a real-time chart. I have tried using the SetColor() API, but the line color doesnt change. Any suggestions?

You must be calling SetColor on the wrong object. You need to call it on the SimpleLinePlot object the RTSimpleSingleValuePlot is based on,


            SimpleLinePlot lineplot2 = new SimpleLinePlot(pTransform2, null, attrib2);
            lineplot2.SetFastClipMode(ChartObj.FASTCLIP_X);
            rtPlot2 = new RTSimpleSingleValuePlot(pTransform2, lineplot2, NASDAQChannel);
            chartVu.AddChartObject(rtPlot2);

	
	// Change the line color
	lineplot2.SetColor(Color.Yellow);
