Limitations

Draw mathematical graphs in a coordinate system

Bartley Sharkey

Recent changes

  • You can now create animations that show what happens when a constant changes
  • You can now choose default settings for save as image options
  • The character map now has full Unicode support under Windows 2000/XP
  • Text labels may now be rotated vertical from the context menu under Windows 2000/XP
  • You can now specify an interception with the y-axis for the built-in trendlines
  • Chinese (traditional), Mongolian, Swedish and Polish translations added
  • Added option to scale the user interface
  • The Euler beta function has been renamed from B to Beta to make B available as a custom constant

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

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.

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) or metafile (emf).

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. Excel.

Calculate

Graph can help you calculate the area under a function in a given interval and the distance along the curve between two points on the function.

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

You can create series of points with different markers, colors and size.

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

Graph can insert shadings used to mark an area related to a function. Shadings may be created with different styles and colors in a user specified interval.

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.

"wonderful, ... but expression should be like EquationEditor"

Very good and userfriendly. It's very easy to include a graph into a word processor (e.i. Word) and see real time the effects on moving and zooming both graph and window. Only 1 increasable point: 1) The "etichetta" should include the equation in mathematical form (as is in Equation Editor of Office), not in textual form (as is in Graph).

Now, I must enter the equation for Graph ed re-enter it as Etichetta using EquatiorEditor (double work and possible errors).

Again, many thanks for your job!

Steve

Pros
  • A lot of functions
  • Many languages
  • Quick
  • Easy and direct import of the graph
Cons
  • Double entering of the expression (very heavy and dangerous)!
  • sqrt and sqr : it's difficult to understand the difference
  • Help: good, but better with some examples of fuctions (e.g. sqr vs sqrt)
