When I plot y=x^2 from an external file of data points I get a different curve when compared to what is drawn if I use the Rhino Parabola command (either form), which seems to draw a more open curve, something like y=2x^2.

I can then drag the endpoints of the parabola to match my plotted y=x^2 curve, but I’d rather specify it directly.

- What am I missing here?
- What is the equation of the Parabola plotted by Rhino?
- Can this command plot the y=x^2 curve?

Every year High School math gets further away from me, so admittedly, that might be my problem.

Thanks for your help,
