Thanks for a useful program. I have used Maxima on the PC before, however it does not offer the same ease of layout as SMath does. It would be great to graphs that are not functions though.

Is is possible to get a 2D plot for an elipse and a vertical line? (Version .75 on Windows XP and on Windows Mobile 5)
So far I have not been able to do so...although I see in the old version that it was possible.

Hello. You're absolutely right, version 0.50 (0.50.4) is able to plot these graphs because it has support of multiple graphs onto one canvas. Last versions of SMath Studio can't do it. An ability to plot multiple functions graphs will be added soon.

Next release will be able to plot multiple graphs into canvas.
