- 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.
