Hi Hazen: As of revision 11781, I have solved the two issues for cairo superscript and subscript vertical spacing that I identified in the previous commit message. The first issue (asymmetry between vertical offsets for superscripts and subscripts) was caused by differences in zero point for the character coordinate systems for PLplot and cairo. The second issue (superscript/subscript spacing being independent of original font height rather than proportional to that quantity) was caused by bad Pango Markup language documentation for the units of rise. (I have inferred the correct units for rise via experimentation).
I will take a look at how superscript and subscript spacing is handled for the qt devices to see if similar issues there need correcting. BTW, this whole superscript/subscript vertical spacing review for cairo and qt devices came about because I was originally getting such different results for the xcairo and xwin devices concerning the placement of exponents that are used by plbox (which is called by plcolorbar) when the axes on the colorbar are badly scaled. The second issue was particularly killing me in that case because colorbars have relative small viewports and therefore small font sizes. I hope to return to working on plcolorbar bounding-box issues shortly. Alan __________________________ Alan W.
