Introduction

What does GraphDraw do?

GraphDraw allows the entry, and editing, of x,y values, and the data may then be fit to

and the results displayed graphically.

A number of options for obtaining hard copy exist (saving as a !Draw file, or printing via any standard RISC OS printer driver), and the drawfiles can be exported into any other application that is able to load such files. The fitted line may also be exported to MultiPlot, which allows the combination of a number of graphs.

GraphDraw provides interactive help in conjunction with !Help or !Bubblehelp.

GraphDraw is freely available, and is undergoing continual development. The latest version can be obtained from the author's web site, at http://www.chris-johnson.org/software/. The author is always ready to listen to bug reports, comments and suggestions and will try to implement such suggestions where feasable.


Installation

For a new installation, simply drag and drop the GraphDraw application into the directory of your choice.

If you have a previous copy of GraphDraw you have two choices.


Using GraphDraw

GraphDraw 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 may also be started by double clicking on any !GraphDraw data file in a directory viewer. This will only work if the !GraphDraw application has been 'seen' by the filer, so that the filer knows to run !GraphDraw before loading the file. If the application is started in this way, 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.


The iconbar menu

The iconbar icon menu offers the following options.

ibarmenu.png - 4KbInfo  –  this leads to the standard information window, which also contains a web button, allowing a quick way of accessing the download site.

Help...  –  will launch the documentation (this file) in the default browser.

New  –  will open a new data input window, assuming the limit to open windows has not been reached (currently four input windows). The same action can be achieved by simply clicking with SELECT (the left mouse button) on the GraphDraw iconbar icon.

See the page Data input for more details on data input.

Choices...  –  will open the application choices dialogue, A full description of the features available is given in the Choices page.

Quit  –  will remove GraphDraw from the iconbar and terminate the program. If there is any unsaved data then a warning will be issued, and the data can be saved or discarded as appropriate.

Screenshots

All the screen shots in these pages were obtained using Snapper, a versatile screen capture application.

Snapper is available from http://www.chris-johnson.org.uk/software/snap.html


These pages are best viewed in a CSS compliant browser. For RISC OS, Netsurf would be the browser of choice.
