I am looking to add a tertiary Y-axis to my chart. I was searching through the internet and came across Jon Peltier's page:
However, I think he nomore has the process of adding a tertiary axis on the page. It would be nice if someone could point to the resource if it is available anywhere else. Any other pointers would also be appreciated.
Also would it be possible to hide the markers and the labels of the tertiary axis?
