Graphulator is a numerical graphing calculator for 2 or 3 variable equations. Plot both functions and non-functions. Includes data output! Now includes numerical calculus.

Scientific calculator.
Absolute values.
Scientific notation.
Basic Calculator.
Function calculator.
Two variable calculator.
Three variable calculator.
Numerical analysis.

Drag grid or use controls to move or change the scale.
Drag three variable grid to rotate.

Graphulator can miss non-functions 1/50 the grid scale. The user can adjust the accuracy or change the grid scale including adjusting the width and height independently.

Graphulator boasts being the only calculator which can perform calculus on non-functions numerically (equations which cannot be reduced to a function). It should be noted that these derivatives differ from standard calculus.

Graphulator boasts being the only numerical calculator which can plot three variable non-functions.
(Equations of the form f(xyz) = f(xyz)).

Another Half Baked Utility...


There are so many issues.... Where to start:

Windows are clipped when dragged to the right on 27" LED monitor.
They just start to disappear at the 2/3 point.

When this utility is running you cannot click in any other window.
It commands all input.

It seems impossible to graph anything.
It's probably possible... But how?

I quit exploring at this point.

Needs a lot of work.

Thanks ... Ken
