Hi Smath Team,
Great tool!

Sometimes a plot does not generate a waveform. I suspect it has something to do with units. Sometime when I start over, or change the order it works, but cannot figure it out. I have attached an recent example. Using 0.96 (build 4909).

You just zoom on the chart that it concerns
Scale: if you roll your mouse wheel it zooms both axes together. If you hold 'control' keyboard key (CTRL) at the same time it just zooms the vertical axis;if you use the mouse wheel holding the 'shift' keyboard key (↑) it zooms the horizontal axis.

Scaling your plot by orders of magnitude with the mousewheel won't probably be fun. Better use appropriate scaling factors (units in your case)

Thank you both for your replies. Both methods worked (obviously now) - I will pay more attention to scaling from now on.
