This routine is a class for creating scientific and business
charts. To run the test data extract the files with
	tar -zxvf phplot-4.0.2.tar.gz 
and then point your browser to 
	examples/format-chart.php.

There are some configuration settings that you will need
to make based on your setup. 

1. File Type: Depending on the version of GD you are using, 
you may or may not have GIF or PNG file ability. That is 
set with the function. 
	SetFileFormat("<filetype>") where <filetype> is png, gif, jpeg, ...
or edit the file phplot.php and make the line
	var $file_format = "<filetype>";

2. TTF: If you have TTF installed then use 
	SetUseTTF("1");
otherwise use
	SetUseTTF("0");

Everything else should be independent of what version you are using.
This has been tested with PHP3, PHP4, GD1.2 and GD 3.8. 

To start with a test, see format_chart.php

--------------------------
Compatibility Note: If you are using PHP3 earlier than version 3.0.2 then 
you need to change one line in phplot.php. Change 
	ImageColorResolve 
to 
	ImageColorAllocate
