That did the trick! After playing with it, I noticed it only happened when I changed to a motor where the top number in the power column reached four digits.

I also played around with some of the other features.

Exporting to an image is neat, except the bitmap is black and white.

Found another bug (sorry). If you right click the graph, select "visible items", then select "scale items", a box comes up. If you move the mouse over the box, an error appears:

You will lose any unsaved work. For assistance in resolving this problem, please relaunch LabVIEW, or contact National Instruments.
An interesting thing I've noted. Max motor efficiency for XL motors is generally accepted as being at around 35k rpm. But, If I increase the voltage higher and higher, the efficiency increases and for a much wider/flatter range. However, the rpm for this is about 140k rpm and the power is on the high side at over 800w. I assume these graphs assume "ideal" magnets and super bearings? :)
