   1  This routine is a class for creating scientific and business
   2  charts. To run the test data extract the files with
   3      tar -zxvf phplot-4.0.2.tar.gz 
   4  and then point your browser to 
   5      examples/format-chart.php.
   6  
   7  There are some configuration settings that you will need
   8  to make based on your setup. 
   9  
  10  1. File Type: Depending on the version of GD you are using, 
  11  you may or may not have GIF or PNG file ability. That is 
  12  set with the function. 
  13      SetFileFormat("<filetype>") where <filetype> is png, gif, jpeg, ...
  14  or edit the file phplot.php and make the line
  15      var $file_format = "<filetype>";
  16  
  17  2. TTF: If you have TTF installed then use 
  18      SetUseTTF("1");
  19  otherwise use
  20      SetUseTTF("0");
  21  
  22  Everything else should be independent of what version you are using.
  23  This has been tested with PHP3, PHP4, GD1.2 and GD 3.8.
