Graph for Windows

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.

Draw functions

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.

Interact with other programs

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

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

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. Excel.

Calculate

The program can also show the first derivative of a function, and create tangents and normal lines to a function at given coordinates.

Point series and trendlines

Data for a point series can be imported from other programs, e. g. Microsoft Excel. It is possible to create a line of best fit from the data in a point series, either from one of the built-in models or from a user specified model.

Shadings and labels

In addition to the optional legend used to describe each function, a label may be added anywhere in the system. A label can contain text with different fonts, images and objects created in other programs.
