Demo_PISERIES program shows blank screen

[toml_12953]

I'm trying to run the Demo_PISERIES program from the TEXTOUT Help screen.

All I get is a blank, white screen. Other graphics programs I wrote myself work fine so I'm pretty sure the hardware is good. It's a G2 with the latest Beta firmware.

Rad/deg setting problem? (Just a guess, did not look at the source)

What are your values for Xmin, Xmax, Ymin and Ymax? These are defining the visible part of the cartesian plane. It should match with the area where the TEXTOUT instructions in the Demo_PISERIES program are printing.
Try with: Xmin=-10, Xmax=10, Ymin=-10, Ymax=10

Hello,

I just tried it and the program worked fine...
My best guess is that, since the program is using TEXTOUT and not TEXTOUT_P, you have a non-default value for the cartesian plan.
Select function app, go to plot setup and reset the values (shift clear), it should then work.

Quite correct! I had just plotted sin/cos/tan curves and didn't change the coordinates back. When I changed them to x: -10 to 10, y:-10 to 10 the demo worked.

Thanks to all who answered!
