Problem displayng input PSD curves

[jujumoi]

Good afternoon,
I'm trying to plot the PSD input curve (from a PSD table) using PSDGRAPH command. The problem is that the graph displayed doesn't show any data (dot's or solid lines).
I'm using as an example the following commands:

PSDFRQ,1, ,100,400,1200,2500,
PSDVAL,1,.02,.05,.05,.01,
PSDGRAPH,1

Does anyone have any suggstions?
Thanks in Advance

Juliano.

Nevermind, It was a problem with my Video Card. It's all ok now. Thanks for your attention.
