Would be another useful plot to include alongside Skew-T. From a support email:

Wanted:

My data will be plotted in temperature, potential temperature pairs in a coordinate system rotated by -45 degrees. My plot axis will be in the original unrotated coordinate system so I still have a rectangular plot and the axis coordinates will be linked by a transformation to the data coordinates so that labelling the axis would be a simple case of performing this transformation on the data coordinates of the label and this would put the label in the correct place on the axis coordinates.

Problem:

I can easily rotate the data coordinates -45 degrees, however I’m struggling to find a way to keep the axis in the original coordinate system and link them to the correct data points. In the Skew-T example, the axis and ticks have all been adjusted separately - I feel like this should be easier in a tephigram as the x and y axis are still perpendicular. I do not know whether what I have described above is actually possible or not - perhaps you could advise!
