dot

Hi everyone,

I try to create diagrams for MPLUS analyses with dot from the graphviz package. Does anybody have experience with using dot to visualize structural equation models/latent class mixture models? There is especially one feature that I can't figure out how to do beautifully:

I need arrows from nodes to the center of another arrow like

           C
           |
           |
           V
   A ------------> B

I tried to insert an invisible node at the intersection of the arrows. This, however, results in a "cracked" A--->B arrow because dot does represent it as two independent arrows. Is this even possible with dot?

Thanks for suggestions and help!

Gregor
