[pstricks] Flow diagram in pdf

[s khan]

Hello:
Could you pl help me out? The problem is:

I have made a flow diagram with psmatrix environment (like the example found 
at http://tug.org/PSTricks/main.cgi?file=psmatrix/psmatrix#flowchart). Its 
size looks ok in dvi output, but when I convert it to pdf using the commands

latex myfile.tex
dvips myfile.dvi
ps2pdf –t a4 myfile.ps

the flow diagram takes the whole page including the margins! Could you pl 
tell me how to control the size of the diagram in pdf output?

I have two flow diagrams, both works the same way!

I have searched the archive extensively without success.  Please help me 
out.


Regards.
