!GraphDraw, © Chris Johnson, 1990 - 1995
What this software does
=======================
It allows the entry of the x and y values for a number of
data, and the data may then be fit to
• best straight line
• best parabola
• a cubic spline curve
• a polynomial of order up to 6
The resulting graphs may be saved as a !Draw file, or
printed via any standard RISC-OS printer driver.
Use of !GraphDraw
=================
Running the application
-----------------------
This software is fully RISC-OS compatible, and is
multi-tasking. It can be run from the desktop in all the
standard ways.
Double clicking on the !GraphDraw icon in a directory viewer
will install its icon on the icon bar.
Clicking SELECT on the iconbar icon will open an empty edit
window, into which the pairs of x,y data may be entered.
Full scrolling and editing facilities are available during
data entry.
The application can also be started by double clicking on a
data file of !GraphDraw format. In this case, besides the
icon appearing on the icon bar, the edit window will be
opened with the contents of the data file displayed, for
further editing if necessary. A data file may also be
dragged, either into the edit window, or to the iconbar
icon. The data will be loaded, overwriting any data that had
previously been entered.
Full interactive help is available, via !Help or
!BubbleHelp, and additional explanation is available from
several of the application menus.
