Sine waves with proper scaling?

OK, I think I figgered it out.  I set up a wave with 1000 points for each second, and used 1/500*PI as the scaling factor.  This means that wave =sin PI*x is properly scaled.  I'll set up another version with more points per second I guess. 

Since you seem to have figured out your issue this may not be necessary, but maybe you want to have a look at setting up a proper time axis:

Thanks - I'm going to definitely check that out.  As it turns out, my declaration of victory was premature - my solution above was totally whacky.  I woke up the next morning and realized that I was making this way too complicated.  No reason to do anything with PI in the scaling factor!  (Was I drunk?  Stoned? Both? And also tired?  And maybe stupid on top of all of the above?)

Seriously, I don't know what I was thinking.  Time is still time, after all.

Right- time is time. If you want 1000 points spanning one second, and then fill it with a sine wave with a frequency of 1 second, do this:

•make/n=1001 junk         // 1001: one point at zero and then close the 1 second interval
•setscale/I x 0,1,junk        // /I flag means first point at 0, last at 1
•junk = sin(2*pi*x)           // go around 2 pi in one second
•display junk
•ModifyGraph zero(left)=1

The Getting Started help has a nice description of how the X scaling works. Plus, you can read about wave assignments and all the wonderful things you can do: DisplayHelpTopic "Waveform Arithmetic and Assignment"
