An in-depth reading of PHP Statistical chart classes _php Tutorial

By using us to

Google Chart API can produce a variety of statistical charts, currently support line chart, column chart, pie chart, scatter chart, graph. The Google Charts API Code page has detailed instructions for using this API, but it's also a bit cumbersome. Today, I found someone who developed a PHP statistical chart class for this area, and also included three examples, and I'll pick an example to show you how to use it with one of my projects:

2. < ? PHP
4. Include (' GoogChart.class.php ');
6. Import Google Chart API classes
8. $ Chart = New Googchart ();
10. Instantiate a Googchart object
12. $ Servers = get_max_servers ();
14. Get 17fav.com Favorite Service rankings
16. $ Data = Array ();//Initialize Data
18. foreach ($servers as $server) {
20. $data ["$server->server_name"] = $server- >
    server_number/100;
22. Here, except for 100, it was discovered when the test was
    The Chart API does not support >=100 values.
24. }
26. $ Color = Array (
28. ' #FF6600,
30. ' #FFB380,
32. ' #FFD9BF ',
34. ' #DFBEA7,
36. ' #BF8660,
38. ' #AA6639,
40. ); Set the color of an image
42. $chart- > setchartattrs (Array (
44. ' type ' = > ' pie ',//pie chart
46. ' title ' = > ' Favorites & Shares ',//image name
48. ' data ' = > $data,//image data
50. ' size ' = > Array (468, 300),//Image size
52. ' Color ' = > $color//Image Color
54. ));
56. Echo $chart; Output image
58. ?>

The above is the specific implementation of the PHP statistical chart class.
