I am using feynmp to generate Feynman diagrams with pdflatex. Everything seems to be working but my labels are not showing up.

What is wrong?


% Needed to interpret generated *.1, *.2 etc. as ps files.

Here is a vertex for a local potential in momentum space:
    % Note that the size is given in normal parentheses instead of curly
    % brackets in units of \unitlength (default 1pt). 
    \fmfleft{i1,i2} % Define external vertices from bottom to top 

    % These labels are missing! 

Save this to tst.tex and compile with:

pdflatex tst
mpost fgraphs
pdflatex tst
pdflatex tst
  • I have removed the spacing "noise" from the MWE: It is now in this question.

Use the starred form \begin{fmfgraph*}.

    This workes, but the labels are outside the bounding box and mix in with the surrounding text. Any way to work around this nicely? Jun 13, 2015 at 9:01
