  This program adds to the many that plots data on a graph- but this has one 
important differance. It is much better 8->.
  This program was started when a friend wrote something like this for the
Acorn Archimedes. It was a program to analyse share prices- but the graphs 
were terrible. I thought that I could improve on them and this program was 
born.

  If you like this program then please send in the registration fee of £7.50
to me at:

                 112 Crayford Road-

                 England-
                 DE24 0HQ.  
  
  In return you should recieve GraphPro V2.0- I haven't finished it as yet
(24-7-93) but it should be ready soon.
  V2.0 can handle multiple data sets- has keyboard shortcuts- more options
and I don't know what else. I won't be sure what it can do until I have 
finished it!


Instructions for V1.1

  The new version is a lot faster and has a better interface. I don't think 
that the interface is too bad for a first attempt at a WIMP system.
  The core of the program has not changed much- There are some new windows 
and a much better button system.

The input window:

New:    Clears all data - you will be asked if you are sure.
Input:  Enter data.
Edit:   I haven't managed to improve this much but it is faster and (normally) 
        works properly!


The Data window:

Print:  Sends list of data points to a printer. NOTE:- Do NOT use this if you
        don't have a printer plugged in as the computer will hang.
Graph:  Brings up a new menu:

        Show:   Put graph on screen.
        Clear:  Clear graph and all other lines.
        Fit:    Draw last calculated line of best fit.
        Title:  Title graph - enter x- y- and main screen title. These will
        be saved along with the file on disk.
        Range:  Enter part of graph to display.
        Dump:   Dump graph to printer or file.

List:   Shows list of data points on screen.
Info:   Shows various internal info - don't worry if you don't understand 
        it- it is mainly for debugging.


Files window:

Disk:   Gives a menu - guess at this one- it should be obvious.
Conf:   Change the configuration of the program. 
Docs:   Show this file with a new reader.  
Vers:   Bring up version information. 
Quit:   Obvious innit.

Analyse window:

Nothing new use slider at the side to view more options.

Configuration:

A new option!

1. Sound.
This produces a small squeek when a button is pressed or an operation is
finished

2. Printer.
If you have printer connected - selecting this option will cause the program
to ask if you want to print the last output.

3. Errors saving to disk.
This is only kept in as a debug option.

4. Error samples.
In the event of a minor error you get a well known android saying.
If there is a major system error you will get the Awooga warning!
(It might be best to turn these off 8->)

5. Printer echo.
This causes the program to automatically dump any calculations to the
printer.

6. PCL Printer.
Only select this option if you have a PCL printer (like a deskjet or
laserjet) it provides better text formatting.

The next part is on another page.

Current program directory is where all the program files are stored on disk.
If you install the program on hard disk you will need to alter these to
point to the directory that the program is stored in.

Datafiles directory is where all the .GRA files are stored - see above.

Screendump directory is where the program will save a copy of the graph in 
IFF format if you select dump to file.

Known Bugs:

Don't bother telling me about these.

1. if the PCL printer option is turned on in the preferences - the computer
will hang whenever you start the program if you don't have a printer 
connected. It does this as the extended printing options are switched on at
the start of the program and if the program cannot find a printer it waits
until one is connected.
2. The screen dump options will ignore the printer on/off in the 
configuration.
3. Program sometimes gets locked into an error and will not quit - use 
CTRL+C to stop.
4. Range routine not perfect - only wrote it on 27-5-93.

New features:

1. General speed increase - optimised code of analysis routines etc.
2. MUCH better interface.
3. Working screen dump option.
4. Configuration menu.
5. System error handling - no longer crashes computer.

If you like this prog. then please send me the registration fee- it is Soooo
cheap compared to what you would pay for a PC Program 8->.
