How can I add an axes to a figure, but specify the transform from axes coordinates to figure coordinates? I want a set of axes (ticks, spines, data, everything) that are rotated?
Figure.add_axes  accepts a box left-bottom-width-height axis aligned box specification. I can’t follow in the code where a transform is made out of that, but I basically want a generic transform. Do tick labels, ticks, titles, etc. assume that the axes-to-figure transform is purely a translation?
