<br>Dear all,<br>I have a problem with pscustom. I want to show the area under parabol x^2. <br><br>The problem is that I got unwanted hatched area.<br><br>In next code, the first picture is the one I want (and don't work): shadow x^2 from 0 to 1.<br>
Then, I repeated but from -1 to 1. And there, the result is as expected. <br><br>Maybe I don't understand how I should close the path in pscustom (??).<br>Thank you in advance,<br><br><br>\documentclass[a4paper]{article}<br>
