Geometry App scaling

[Brad Barton]

I'm trying to work through the example in the user's guide, which has me plotting a sine wave. When viewing the function though, the Prime plots it out in a very long curve with almost no height. I've tried re-scaling the horizontal and vertical scales using Xrng and Yrng, but the aspect ratio seems to be stuck. If I scale the X parameter, the Y parameter goes right along with it. Zoom>Box also seems to force a constant aspect ratio.

Is there a setting or flag that allows me to scale these parameters separately? I haven't been able to find it in the manual, nor does poking around in the help section seem to reveal the answer. I'm using the emulator rev. 6031.
