PISAPLOT allows the use of PGPLOT text escape sequences. It also has parameters controlling the size of the annotations, the presence of annotations, the number of tick mark and the thickness of the lines. So for instance the plot on the front page of this document was produced using the commands.
# pisafind frame(80:210,115:260) reset accept
# pisaplot device=pscript_p pltitl="\fr Objects located by PISAFIND"
abslab="\fr X position (pixels)"
ordlab="\fr Y position (pixels)" thick=2 annoscale=2.5
Hence the labels were written using a Roman font.
