[comp.text.tex] Tex-Makros for drawing graphs

bause@anton.informatik.uni-dortmund.de ( ??? Bause ???) (09/07/90)

I'm looking for an easy way to draw graphs especially Petri Nets (using
LaTeX). Looking at Lamport's LaTeX-Book it's easy to draw boxes and circles,
but how can the connections between nodes are drawn.
Is there a possibilty for something like:

     \put(x,y){\NODE_TYPE1{node1}}
     \put(a,b){\NODE_TYPE2{node2}}
     \connect{node1,node2}   
              and a directed arc is drawn from the border of node1 to the 
              border of node2.


Please answer by e-mail, I'll summarize to the net.

Thanks for the hints I've received. In the meantime I've read about
the program TeXcad, which is PD and included in the emtex package (hope so).
I've got a copy for IBM ATs. It has a graphical user interface similar to
MacDraw, sundraw etc. and produces LaTeX output (picture environment). 
All graphical objects which are available in LaTeXs picture environment 
are supported by TeXcad.
