Locus - Graph editor

Locus was written to provide a simple yet sophisticated graphing tool to the students I teach. It is free to use and can be configured to be as simple or as complex as you could wish.

It has the following features:

Formula based graph plotting in five operational modes:
- Cartesian (non-parametric)
- Polar (non-parametric)
- Cartesian (parametric)
- Polar (parametric)
- Implicit
The user can watch the graph being plotted. This is very useful and educationally important. It is also rare among desktop graph editors.
Formulae can be entered in standard algebraic notation.
Functions can be input in user defined function notation.
Constants can be used
\'Families‘ of graphs can be plotted
Commonly used functions in each of the five modes can be saved and edited.
You can choose fully automatic axis scaling or have complete manual control.
It features a drag box zoom and an automated zoom out facility.
The graph can be moved up, down, right and left as required.
It can analyse gradients of functions and areas under graphs and draw gradient and integral functions.
Bi-variate data sets in Text, CSV or SID formats can be imported
User defined transformations of datasets using matrices or descriptions can be applied.
Statistical information including means, standard deviations and least squares regression lines can be calculated.
Data can be saved in Text, CSV, TSV, SID, Bitmap, GIF or LocFile format.
The user can print from the application.
All user definable features can be saved as defaults.
