Graphs
|
ChartDraw
|
Allows the production of a range of charts, of the following types:
- line graphs
- stacked bargraphs
- grouped bargraphs
- pie graphs

FnPlotter
|
Allows the entry of up to four functions, in BASIC format, and will produce a data file of the correct format for loading into MultiPlot for graphical display of the functions; thus the graphical functions may be overlaid with other graphs produced by GraphDraw, for example

|
GraphDraw
|
Allows the entry of the x and y values for a data which may then be fit to:
- best straight line
- best parabola
- a cubic spline curve
- a polynomial of order up to 6
and the results displayed graphically, with a wide range of display and export options

MultiPlot
|
Allows the plotting of up to eight graphs on the same set of axes; suitable data files may be produced using GraphDraw or FnPlotter, for example

Surface
|
A very simple 3D function (surface) plotter which takes as input a text file containing the x, y, and z data for a function of the form z = f(x,y) and draws a 3D view of the function
|

|
3DFnEdit
|
Front-end application for Surface which allows you to enter a function of the form z = f(x,y) and produces a file in the correct format for loading into the Surface
