Thanks, have now got the 2nd scale showing, but is the same scale range the one on the left, I need it to be as per the range for bar2 which your demo shoes.
m_BlueAxis = ((NCartesianAxisCollection)nChart.Axes).AddCustomAxis(AxisOrientation.Vertical, AxisDockZone.FrontRight);
m_BlueAxis.Anchor = new NDockAxisAnchor(AxisDockZone.FrontRight, true);
nBar2.DisplayOnAxis(m_BlueAxis.AxisId, true);
