Latex primed regression?

Alexander_Wagner · April 16, 2012, 12:53am

Dear Matplotlib users,

Mathtext primed used to be rendered correctly in 1.0.0 like so

But now they look tiny and badly spaced in 1.1.0 like so

I haven't tried with all fonts, but it is the case with Bitstream Vera Sans and Helvetica. Can anyone confirm?

If I use the LaTeX renderer, it looks correct.

Many thanks,
Alex

What is the math string you are using? I can’t seem to reproduce
this with:

   "$D_{40}\prime\prime$"

What are your math-related rcParams?

I’m using $D_{40}^{\prime\prime}$

I think this is how prime should be used in latex, or?

Using mathtext, when i don't include "^" I get

![dcfbjdhc.png|106x47](upload://yifO2aodxNyb3VVzvohKr6tMi4v.png)

Here, the spacing between the primed is too far apart. Also, in

regular latex, primed is usually in superscript, i think, otherwise,
without the ‘^’ one gets:

![hchieagh.png|104x53](upload://5QotR0LW4eWSYbQ6FJpaiTlzYwa.png)

I hope i'm not totally wrong, but the mathtext interpreter seems to

be inconsistent with the regular latex notation, and the primes are
also too widely spaced. I guess it’s not that important, it’s just
aesthetically a bit unsatisfactory.

Best wishes,
Alex

ps. my math-related rcParams are just the defaults, i think

`mathtext.cal : cursive

  mathtext.rm  : serif

  mathtext.tt  : monospace

  mathtext.it  : serif:italic

  mathtext.bf  : serif:bold

  mathtext.sf  : sans

  mathtext.fontset : cm

  mathtext.fallback_to_cm : True

  mathtext.default : it `

This bug was introduced in PR #54. That tried to fix the behavior
of the apostrophe character, but inadvertently made primes smaller
as well. The fix is revert prime to its old size, but make the
apostrophe equivalent to “^\prime”.

Are you able to test the following pull request and ensure that it

resolves your issues?

Thanks, Mike, everything primed looks nice again.
