\nWhen I compiled PHP on my LinuxPPC box, I didn’t have GD installed and
\n didn’t want to add another layer of complexity by compiling it in. GD
\n will let you do all kinds of cool things – creating gifs, complex charts, etc,
\n if you use libraries from the Sample Code Archive here on this site and PHP’s
\n built in functionality.<\/div>\n
\nI didn’t want the lack of GD to stifle me too much, so I started hunting around
\n for a way to generate html-based graphs and charts. Fortunately, someone
\n had already gone to the trouble of writing up a class to handle that.
\n at
\n WebGuys<\/a>
\n provided a nifty class called HTML_Graphs.<\/a><\/div>\n
\nAt first, I was a little taken back by the complexity of the class. It does
\nall kinds of things, from vertical bar charts to multiple horizontal bar charts.
\nBecause I knew I was going to use the class a lot, I spent some time creating a
\ncouple of wrapper functions.<\/div>\n
\nMany of the functions of the class don’t need to be used for basic graphing,
\nwhich is what I am showing here. For instance, I don’t see any need to
\n go into detail on creating multiple charts at once. And vertical charts
\nare created as easily as horizontal charts – just change the “type” parameter
\nin the GraphIt() function that I detail elsewhere.<\/div>\n
\nSo let’s get started. I will at first lay out the functions I have written,
\nand then we’ll talk about a specific use for them.<\/div>\n<\/div>\n
