Does the Infragistics Webchart component have the ability to have threshold lines similar to the one on this demo: http://demos6.dundas.com/powerflo/

The red line on this demo serves as the threshold line. I would like to implement the same thing using Infragistics Webchart.

Please let me know if this is possible or not. Thanks!

If you use a 2D chart, you can use FillSceneGraph event to custom draw the line.
You can try the following example that implements FillSceneGraph:

which has a lot of good information regarding this topic. I hope this helps -Paul

Any samples showing how to draw a line? The samples here show rectangles and circles. Thanks!

Well it isn't much different for Lines. Create a line with the constructor: Line l = new Line(System.Drawing.Point p1, System.Drawing.Point p2) You can get the coordinates for the first point as shown in the tutorial using Map() and then the second point you can provide with the information you already have. It should hopefully be pretty self explanatory from there.
