Let us assume that we have a graph created by a program different from LaTeX (that is not with PStricks or Tikz). I was wandering if it is possible to incorporate mathematical symbols on that graph using a TeX editor.

Thank you.

    \stackinset from the stackengine package. See page 20 of the documentation in stackengine.pdf at ctan.org/tex-archive/macros/latex/contrib/stackengine Apr 14, 2014 at 18:44
  • If it is an .eps file and there is some text in this graph file, the text can be replaced from LaTeX using the \psfrag command from the corresponding package, but this collides with pdflatex nowadays a little bit

  • @StevenB.Segletes this looks awesome. I will give it a try when I have time. I suppose the package is already in the MikTeX right? Apr 14, 2014 at 18:48
  • @PantelisKazakis The package is about a year old. I think it is part of MikTeX, but if not, you can grab it from CTAN and place the .sty file in your working directory until you figure out how to install it. Apr 14, 2014 at 18:52

    Package overpic can do it without TikZ. Apr 14, 2014 at 19:26

Basically, this is using the example of the stackengine documentation, adapted for use in math mode with the addition of \stackMath in the preamble.

The routine you want is \stackinset which has 6 arguments, \stackinset{H-anchor}{H-offset}{V-anchor}{V-offset}{inset}{underlying anchor image}. As shown here, it can be nested and the insets themselves can be stacks.

\stackinset{l}{ .1in}{b}{.2in}{y=mx+b}{%
\stackinset{r}{ .1in}{t}{.2in}{\Longstack{F_x=ma_x\\F_y=ma_y}}{%
\stackinset{r}{ .8in}{b}{.6in}{\psi^2=0}{%
\stackinset{r}{ .1in}{c}{.0in}{\imgi}{%

    @cmhughes I specifically said that I want to manipulate a graph not made by PStricks or Tikz. Apr 14, 2014 at 18:55

    @PantelisKazakis: The linked question is about drawing on an image... and that's that. That image could have been made using PStricks, TikZ, a camera, or whatever...

  • @Werner I will follow Steve's way. It is quite neat! Apr 14, 2014 at 19:03
