I have exported my curve from matplotlib using the following guide. But there is a problem with reference at y-axis label. You can see it on screenshot: enter image description here

The red square should be at "1" in "(s. 1)". I did it with \ref{...} and included the hyperref library. The label will be initiated with the following line in pgf file:

\pgftext[x=0.469752in,y=2.376000in,,bottom,rotate=90.000000]{\color{textcolor}\rmfamily\fontsize{10.000000}{12.000000}\selectfont Energiedichte \LaTeX \(\displaystyle \varphi\) (s. \ref{formel:wichtig}) [Js]}%

It seems that \ref (and even \hyperref) annotation doesn't use rotate parameter. Is it some kind of bug in it? What can be a possible way of soltion this problem?

  • Thanks for your reply @JohnKormylo. There is no axis environment. I have shared the related code to pastebin link – Leonid Lunin May 12 '20 at 13:21

It does look like a problem specific to \pgftext. You can fix it by using \rotatebox instead.

\pgftext[x=0.469752in,y=2.376000in]{\rotatebox{90}{\color{black}\rmfamily\fontsize{10.000000}{12.000000}\selectfont Energiedichte \LaTeX \(\displaystyle \varphi\) (s. \ref{formel:wichtig}) [Js]}}%
  • That helps! But now the label overlapped the axis screenshot. I understand that this can be fixed with chaning of x coordinate, but how can I calculate the difference of them and where does the problem come from? – Leonid Lunin May 12 '20 at 14:08
  • \rotatebox can adjust the center of rotation. The default is. [origin=bl] or [origin=Bl] so [origin=c] or [origin=cb] should do it. Documentation is from the graphicx manual. – John Kormylo May 12 '20 at 14:23
  • That's true, but doesn't help. Seems like anchorpoint should be right on edge of the box, otherwise it's still the same... – Leonid Lunin May 12 '20 at 14:24
  • Thank you so much for your help. If I am ready to contribute code base can you explain, where the problem occures? In hyperref or basically in ref? – Leonid Lunin May 12 '20 at 21:11
  • You can put a \ref inside a savebox and rotate the savebox, no problem. The weirdness comes from \pgftext. – John Kormylo May 12 '20 at 21:53
