I had seen this converter in the init-images.scm file but it wasn't in 
my distribution so I had decided to skip it.
On your advice, I just installed it to see. The result is the same as 
the export to pdf then convert to ps : not so good on the screen within 
TeXmacs but really good in pdf export and printing.
So I will stay with my previous converter as it is most commonly installed.

To sum up, the TeXgraph plugin will provide two kinds of exports :
1.  direct export to eps (compiled or not)
    -> with a good screen display, a good printing and a good export to 
pdf - but with no transparency at all.
2.  export to pdf (compiled or not) then convert to ps
    -> with a bad screen display, a good printing and a good export to 
pdf - but with a "flattened" transparency

for the second case I use : pdftops $FILE.pdf - (which outputs directly 
to stdout)
pdf2ps gives a better screen display but catastrophic pdf export so I 
didn't keep it.

Thank you for your help.
