Hiya people! I had a thought that it would be nice if I could add an ordinate axis with temperature to some concentration against time charts. Using a popular search engine, I found some workarounds (which I did not all totally understand) using a line from a set of data made to look like an axis using a scaling factor, and placing two charts over each other to look like one.
Furthermore, I found a fairly straightforward way of adding a third axis to a line or bar chart using the combo chart. However, that does not seem to be a good fit with my data (temperature, time and concentration).
Can any of you point me to something that I have missed?
