Functions 2d, Opera application V1.2 Jun 4, 2006 10:07:34 AM

Draw 2D curves from mathematical expressions

Enter a mathematical function and have it plotted on a 2D plane.

------

Equations are entered as a function of x. An example for a unit circle would be:

f(x) = (1-x^2)^(1/2)

There is one main feature that is missing from this release and that is that the axis do not have markings on them. This is due to the limitation of Canvas not being able to write text, however in a later release I will have my own text implementation.

Enjoy!

Nice widget, good if you like a quick plot of function without having to open some full-fledged math program.

One thing I'd like is the ability to zoom x and y separately.
