[Plplot-devel] patch to plbox re placement of exponential labels

[Schwartz, S. J <s.s...@im...>]

I attach a patch to svn 12298 which addresses the following issues:

1  Exponential labels, e.g.  (x10^nn), along vertical axes were absent when driven by plslabelfunc(). This was due to the fact that the call to plmtex was unreachable in the case  if(plsc->label_data) being true.

2  Default height, pos, and just values correspond to the bottom of the left but top of the right vertical axes. I think both should be at the top (but accept this is my humble opinion. These are easy to change.)

3  Default height, pos, and just values are inappropriate for both "l" and "lv" label orientations. To be honest, finding a decent default for this in "v" orientation is pretty difficult.

4  There were other bugs, e.g., in using a "t" option rather than "l" or "lv" to plmtex.

The attached test code illustrates the initial state and the result after my changes to plbox. I made parallel changes to the code in label_box_custom as it is virtually identical here, but don't have source code to test it.

Best wishes
Steve
