FreeWare Experimental Grapher
(C)opyright TakaPuna 1991 Version 1.1
Portions of the codes are (C)opyrighted by Borland International
Command Line Options:
FileName [All Labels] [Starting Ending Labels]
FileName : Data file from a text file
Starting : Starting index to view (integer)
Ending : Ending index to view (integer)
Labels : Axis labels
---------------------------
What the program need to run
-------------------------------
*.bgi file for your monitor must be present in the same drive that you
are running grapher. File 'litt.chr' must also be present. If the file
'litt.chr' is not in the same directory, the program will still work.
-----------------------------
How to use the program
------------------------------
The easiest way to use the program is by using example. If the following
command is invoked at dos prompt assuming the data file is test.dat:
- Grapher test.dat
[ will display all data points ]
- Grapher test.dat All
[ will display all data points (same as above) ]
- Grapher test.dat All X vs Y
[ will display all data points and label the axis X vs Y ]
- Grapher test.dat 1 20
[ will display data points starting from data #1 to #20 ( zooming )]
- Grapher test.dat 1 20 X vs Y
[ will display data points starting from data #1 to #20 and label
axis X vs Y ]
For demo run:
demo1.bat, demo2.bat, demo3.bat, demo4.bat.
------------------------------
Program Limitations
------------------------------
- X must start from lower values so that the graph plotted make sense.
- Not as robust as a spreadsheet.
- Sometimes if the data are so close apart round off errors occurs.
i.e function Round. If that happens, the best bet is to plot it as
zooming (i.e Grapher FileName 1 20 ).

BUGS FROM BEFORE
----------------------------------
- I tried to fix the bug as I find it. Version 1.0 of this program
could not handle zeros as minimum. I've already fix it.
----------------------------
Contacting me
-----------------------------
if you find any bugs what so ever please tell me and I'll try to fix it.
