Topic: No line displaying

I got graph recently and it seems like an interesting program, but when I try to graph a function, for some reason I can't view the line no matter how I attempt to change how the line is displayed. I'm running 32bit Windows Vista. Any ideas about what's going on?

Re: No line displaying

I am not sure I understand you correctly. It sounds a little strange.
Does the program show the coordinate system, but not the functions?
What about the examples installed with Graph? Do they work?
