Graph is an open source application used to draw mathematical
graphs in a coordinate system. Anyone who wants to draw
graphs of functions will find this program useful. The program makes it very easy to visualize a function and Paste It into another program. It is also possible to do some mathematical calculations on the functions.
Why should you use
Graph?
Here are some of the things
Graph can do for you:
Draw functions
Graph can draw normal functions, parameter functions, and polar functions. You can use a lot of built-in functions, e.g. sin, cos, log, etc. You may specify color, width and line style of the
graphs, and the
graphs may me limited to an interval. It is also possible to show a Circle at the ends indicating open or closed interval.
Draw relation
Graph can show any Equation and inequality, for example sin(x) < cos(y) or x^2 + y^2 = 25. You can choose line width and color for the equations, and color and shading style for the inequalities.
Interact with other programs
You can save the coordinate system with
graphs as an image on disk either as a bitmap (bmp), Potable Network
Graphics (png), JPEG, metafile (emf) or Portable Document Format (PDF). You may also copy the coordinate system into another program, e.g. Microsoft Word, either as a normal image or as an OLE object, which may be edited later by double clicking on it.
A lot of options
While still easy to use
Graph has a lot of customization possibilities, e.g. fonts, colors, axes style, grids, etc. The axes, which may by normal or logarithmic, can be placed either by entering specific values, or by moving or zooming with the mouse.
Evaluate
Given an x-coordinate
Graph will calculate the function value and the first two derivatives for any given function. Alternatively the function may be traced with the mouse.
Graph can also fill a table with evaluated function coordinates in a user specified range. Data from the table can easily be copied into another program, e.g.
