[pstricks] problem with pscustom

Dear all,
I have a problem with pscustom. I want to show the area under parabol x^2.

The problem is that I got unwanted hatched area.

In next code, the first picture is the one I want (and don't work): shadow
x^2 from 0 to 1.
Then, I repeated but from -1 to 1. And there, the result is as expected.

Maybe I don't understand how I should close the path in pscustom (??).
Thank you in advance,

  hatchwidth=0.4pt, hatchsep=1.5pt,hatchcolor=blue, unit=1, linewidth=0.7pt}
