Google Chart Class

Goog Chart Class

This page show examples of GphpChart class usages.

• Thanks to Google for a nice, fast, and easy-to-use API : Google Chart API
• There are some limitations to it (who said "labels positions" ? :) ) but it's worth most of the commercial classes anyway.
• I am not Google officiel or whatsoever, just a freelance developer and SEO
• This class is officially in eternal beta : no garanties (it works, though), no cashback (it's free anyway), no extensive support (but the doc is simple)
• I expect Google to update his API in the next few months, so stay tuned

Terms of Use

• This class is free for you to use, and all Google Chart API terms applies (whatever they are)
• A feedback about your usage, and some cool graphs are most welcome
• A link back to this page is appreciated, somewhere on your site

Why use GphpChart class ?

• Easy to use within your PHP backend or website
• Cache images: don't break the API limit ( 50 000 calls a day ) by requesting the same image twice.
• Example usage: http://chart.apis.google.com/chart?cht=lc&chd=t:8.3,16.7,25,33.3,41.7,50,58.3,66.7,75,83.3,91.7,100|69.2,20,81.7,1.7,45,72.5,81.7,54.2,72.5,45,45,72.5&chtt=My+pretty+chart&chs=300x200
• You set :
  
  $lc1 = $array;
  $GphpChart = new GphpChart("lc");
  $GphpChart->title = "My chart";
  $GphpChart->add_data($lc1);
  echo $GphpChart->get_Image_String();
• Which shows the image on the right
• Emulates 95 % of the API functions
