MS Chart Control Two Y Axis

It gets even better:

For using the second Y axis, there is no need for a second chart area. You can decide per serie which axis you want to use with the Series.YAxisType property. Take a look at the documentation on http://msdn.microsoft.com/en-us/library/dd489216.aspx

Here's what did it for me- after I created the chart I added the following lines:

chrtMain.Series[0].YAxisType = AxisType.Primary;
chrtMain.Series[1].YAxisType = AxisType.Secondary;

chrtMain.ChartAreas[0].AxisY2.LineColor = Color.Transparent;
chrtMain.ChartAreas[0].AxisY2.MajorGrid.Enabled = false;
chrtMain.ChartAreas[0].AxisY2.Enabled = AxisEnabled.True;
chrtMain.ChartAreas[0].AxisY2.IsStartedFromZero = chrtMain.ChartAreas[0].AxisY.IsStartedFromZero;

There was no need to superimpose two charts or anything!
