________________________________________
This application provides interactive
help when the !Help application is
active.
________________________________________
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
a. best straight line
b. best parabola
c. a cubic spline curve
d. a polynomial of order up to 6
A number of options for obtaining
various forms of hard copy exist
(saving as a !Draw file, or printing via
any standard RISC-OS printer driver).
________________________________________
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.
The application can also be started by
double clicking on a GraphDraw file. 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.
________________________________________
The Iconbar Menu
Clicking with MENU on the icon offers
the following options:
Info
The standard information box, with
version number. This is the number that
should be quoted in any communication
regarding the application.
Help
Opens this help window
Choices...
Selecting this brings up a dialogue box
that allows a range of options to be
changed, and these changes may be made
permanent so that they become the new
defaults when the application is
subsequently started.
The choices should be self explanatory.
The font names and size can be changed.
To change the font, simply click on the
menu button to the right of the font
name field, when a menu will open with
all the installed fonts shown, from
which a choice can be made. Clicking on
the menu button to the right of the
font size field will raise a menu to
choose the new size.
The type of line (dashed or continuous)
used for producing a graph grid for the
graph may be chosen.
If the "Save graph layout options" is
selected, then all the CURRENT layout
settings will be saved in the default
file, otherwise the old layout default
settings will not altered.
The changes will not come into operation
until the Set button is pressed. If the
cancel button (or the window close icon)
is pressed, the dialogue box is removed
from the screen, and the original
defaults remain in effect. The selection
can be made the new default by clicking
on the save icon. (This option is NOT
available when the application is
running over econet). Note that the
default file is saved within the
!GraphDraw application, therefore, if
the application is being run from a
floppy disc, the filer may request the
disc containing the !GraphDraw
application to be inserted in the disc
drive.
Quit
Terminates the GraphDraw. GraphDraw
offers the chance to save any modified
data before quitting.
________________________________________
Entering Data
Clicking SELECT on the GraphDraw iconbar
icon will open an empty edit window,
into which the pairs of x,y data may be
entered. This version allows a maximum
of 200 data point pairs.
More extensive help is available from
the edit window menu.

particular context.
