Editorial review

All comments (1)
The following review written by one of the Software Informer contributors applies to version 2.0
Graphmatica is a small program designed for students and teachers of Mathematics. With it, you can graph your own equation just typing it over a text field and pressing enter.
Graphmatica is very easy-to-use and have a lot of interesting options.
You can easily switch the graph paper (ex. to show polar coordinates instead of the standard x-y graph). Moreover you can change any graph color: the background, grids, and function line colors can be altered to easily match your needs.
Looking at the math features, after you draw a line over the graph you can easily (I mean 1-click) find derivatives for such equation. The same occurs with numerical integrations: just select the area and the program makes the rest.
Personally, I found this program very interesting. The only drawback is that you could use it just for 30 days, after that you have to pay for it. Another issue to mention is that you have no help at all when typing the equations. If you misspelled something, then you get just an error message. It will be crucial to read carefully the help file before to start using it seriously.


  • Very fast drawing.
  • Complete set of graphs.


  • The errors on equations are not very descriptive.

What's new in version 2.4

New/improved features:

- Curves are now highlighted as you mouse over them or select them in the equation list.
- Added Pick Line Style to the context menu for equations, allowing you to choose from solid, dashed, dotted, and dash-dot line styles.
- Fixed-increment Cartesian, polar, and parametric graphs (i.e. with the step rate specified as a third parameter in the domain) now display as a series of points;
point tables are aligned to display the same values.
- The parser now accepts functions run together with a single-variable parameter, e.g. y=logx.
- Added support for specifying powers of functions before the parameter e.g. y=sin^2x or y=cos²x
- Any equation/inequality that is explicitly specified as x=f(y) is now graphed as a function of y, even if it can be solved for y instead.

Bug fixes:

- Fixed bug which could cause graphs to be drawn slightly past the end of their specified domain.
- Find All Graphs now adjusts the range based only on the requested domain of the equations (rather than the maximum possible values that would be visible on the screen with an unrestricted domain).
- Selection highlighting now uses a dark transparent overlay (instead of a hard to see white overlay) for bright colors other than pure white.
- Fixed a number of issues with graphing inequalities like x < 1/y, where it is important to evaluate asymptotes as a function of y instead of x.
- Fixed a problem which caused ODEs (and implicit Cartesian functions) to fail to register (and later disappear) when evaluation failed due to a non-fatal error (overflow, out of domain, etc.). They now just stop drawing at that point.
- Eliminated extra vertical asymptote drawn as part of y=acot x.
- Fixed cubert(x) function to be defined for x < 0.

Publisher's description

Graphmatica is a powerful, easy-to-use, equation plotter with numerical and calculus features. It provides support for Graph Cartesian functions, relations, and inequalities, plus polar, parametric, and ordinary differential equations. You can print your graphs or copy them to clipboard in bitmap or vector format in black-and-white or color.
