Locus Graph Editor
Locus is Freeware, but if you find the program useful you can make a voluntary contribution of £5.00 by clicking here
As a thank you, this voluntary contribution also entitles you to a free 2 months subscription to the worksheet section of the Sharpe-Maths site.
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)
- 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.
