In-depth interpretation of PHP statistical chart class_PHP tutorial

Using our Google Chart API to create various statistical charts, we currently support line charts, column charts, pie charts, scatter charts, Graph. The Google Charts API Code page has detailed instructions for using this API, but it is still a bit cumbersome. Today I found that someone has developed a PHP statistical chart class in this area, and it also includes three examples. I will choose an example and combine it with one of my own projects to explain how to use it:

1. ?php include( 'GoogChart.class.php' ) ;
2. // Import Google Chart API class
3. $
4. chart = new GoogChart(); //Instantiate a GoogChart object
5. $
6. servers = get_max_servers(); //Get 17fav.com collection service ranking
7. $
8. data = array(); // Initialization data foreach ($servers as $server) {
9. $data["$server-
10. >server_name"] = $server->
    server_number/100; // The reason for excluding 100 here is that during testing, it was found that the Chart API does not support the value of
11. 
    >=100. }
12. $
13. color = array( '#FF6600′,
14. '#FFB380′,
15. '#FFD9BF', 
16. '#DFBEA7′, 
17. '#BF8660′ ,
18. '#AA6639′,
19. ); //Set the color of the image
20. $chart-
21. >setChartAttrs( array( 'type' =
22. > 'pie', // Pie chart 'title' =
23. > 'Collect & Share', // Image name 'data ' =
24. > $data, // Image data 'size' =
25. > array(468, 300), // Image size 'color' =
26. > $color // Image color )) ;
27. echo $chart; // Output image
?>
29. The above is the specific implementation method of the PHP statistical chart class.
