I am using a sans font for my figures. Hence I also want the tick labels of the pgfplots to be in sans. The tick labels, however, are set in a math enviroment. So changing the text font does not change anythings here. I have seen a possible solution here on tex.SE. The problem is that get many error messages like that:
! LaTeX Error: Symbol font `um_fam1' not defined.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.23 \end{axis}
I think the problem is that a non-math font is used with unicode-math
, which is not the intended use case for unicode-math
. I really tried many ways to change the math font to sans, see for example here, but the essence is that a sans math font is not possible.
Since it is not possible to use a sans math font, maybe it is possible to change the pgfplots to use not an mathematical enviroment. I'm asking here, if it is possible to patch pgfplots
to use an non mathematical enviroment for the tick labels? I understand this enviromnent is needed for fractions or some log scales. But I actually don't use those. So I'm fine with a solution ignoring those cases. The only important characters are digits and commas.
