Instruction Manual
------------------

All codes are written in Java, and may be executed on any platform with
Java support.  They have only been tested on windowXP, Windows 98 and
Solaris (Unix), using JDK 1.4.1 and JRE 1.3.1.  To install them, just copy 
the cw*.class file onto the hard disk of your computer.  If the JDK is 
installed on that computer then you may run the program by typing 
"java cw*" from the command line (assuming that you are working in 
the same directory as the cw*.class file).  If the JDK is not installed 
then you may obtain the Java Runtime Engine from Sun, and type 
"jre cw*" instead.(Tim Brailsford (2003))


For program cw2a,cw2b.cw2c.cw2d, the data files and TButils class need to be stored in the same directory as programs' file. And the programs only handle the double numbers. 

When you run program cw2d, it will display the data set of a input file in a console and open a window displaying the pie chart of the data set. 

when you run program cw2e, it will display a dialog for selecting a file and display file data set and its pie chart on a screen. 

Be aware that Unix machine has different font code for text format, so there is no text font difference on unix window. 

In the programs, the colours of pie chart are selected randomly. So it can happen to be the same colour as the panel.
