change Y value of a point in MS Chart


I have an area chart on a form.  When the program is running the points in the chart are changed from time to time. I do the following to change Y value of a point, but the chart isn't getting changed.  What have I missed?

myChart.Series["mySeries"].Points[ 1].SetValueY(100]);

you probably have to call myChart.Update() (I think that's the method...) in order for your chart control to redraw with the new information otherwise the visual won't change even though you did change your point's value.

myChart.Update() didn't work but myChart.Points.ResumeUpdates() did.  I have no idea what was going on but am glad it's working...

myChart.Update() didn't do the trick, somehow. But it makes sense and it showed me the right direction to find the solution.
