[pstricks] gant diagram

Hi,

I want to prepare a gant diagram using the example given by pstricks 
home page.  I did some modifications on the original source code. All 
works cover 48 moths, but I coudn't see all months with only numbers on 
the output. I want to see basic interval for every month. A second 
question, how can I align task names to the right?

Thanks
A. Ustun
