Quote:I think im doing exactly as said,but i have a message "Error:Invalid object" when plot the graphic too.

1. What function were you trying to plot?
2. Do you have complex mode enabled?
3. What number format setting are you using?

I am a bit surprised that you managed to get any error message. Apps currently do not trap errors like programs. If you get an error while running an app, the app just stops and nothing is reported to the user.
