Graphis
-
Version
1.0.1
Graphis is a data visualisation program for 2D (one
independent variable) and 3D (two independent
variables) data. Graph curves can be created from
tabular data , or by using the VBScript scripting
language. The scripting aspects of the program are
made transparent to the user by embedding the entered
function definition inside a standard script behind
the scenes. For example, to plot sin(x), simply enter
y = sin(x) in the script window. The function
definition need not be a single line. It can consist
of multiple lines consisting of constants and
variables defining components of an overall formula.
If required, the script transparency can be turned off
and the full power of VBScript is available to you.
High quality OpenGL graphics is used for all 3D
graphs, and 3D graph quantities such as viewing
position and scaling can be manipulated interactively.
Support for data import is provided via File and Curve
spreadsheets.File Spreadsheets allow data to be
imported from character - delimited text files using
an Excel-like data import feature.Curve Spreadsheets
can be used to build and store specific curves.
Scripted and tabular curves can be plotted on the same
graph allowing comparison of empirical and analytical
data. 3-D graphs can use built-in or user-scripted
colour ramps.The program can be run as an OLE server
inside OLE clients such as Microsoft Word, allowing
OpenGL graphs to be interactively manipulated from
inside Word.
