<DIV>Hello everyone,</DIV>
<DIV> </DIV>
<DIV>I am working on a problem that will show one to hundred thousnad of color curves. There are about thirty points for each curves. To do that I need to new hundred thousand maps and actors and it usually crashes after it shows about twenty thousand curves. So I wonder if there is any better way to draw color curves. The following is part of the code I generated. </DIV>

<DIV>I really appreciate your help.</DIV>

<DIV>Thanks.</DIV>
