CanvasJS是一个JavaScript库，用于轻松为网页创建其他类型的图表。例如条形图，饼图，柱形图，面积图，折线图等。
让我们以需要创建一个图表的示例为例，在该图表中我们可以显示每月销售和购买的产品。我们将考虑两个数组，我们也可以从数据库中考虑它们。一旦我们从数据库中获取数据并将其存储在数组中，它就可以使用canvasJS轻松绘制动态图形。
创建一个文件并将其保存在项目文件夹中。文件名chart_sample.php包含数组形式的数据，其中第一个数组代表购买的产品，第二个数组代表sols产品列表。现在，使用canvasJS绘制图形。
例如：
<"label"=> "Jan", "y"=> $purchased[0]),
array("label"=> "Feb", "y"=> $purchased[1]),
array("label"=> "March", "y"=> $purchased[2]),
array("label"=> "April", "y"=> $purchased[3]),
array("label"=> "May", "y"=> $purchased[4]),
array("label"=> "Jun", "y"=> $purchased[5]),
array("label"=> "July", "y"=> $purchased[6]),
array("label"=> "Aug", "y"=> $purchased[7]),
array("label"=> "Sep", "y"=> $purchased[8]),
array("label"=> "Oct", "y"=> $purchased[9]),
array("label"=> "Nov", "y"=> $purchased[10]),
array("label"=> "Dec", "y"=> $purchased[11])
);
// Data to draw graph for sold products
$dataPoints2 = array(
array("label"=> "Jan", "y"=> $sold[0]),
array("label"=> "Feb", "y"=> $sold[1]),
array("label"=> "March", "y"=> $sold[2]),
array("label"=> "April", "y"=> $sold[3]),
array("label"=> "May", "y"=> $sold[4]),
array("label"=> "Jun", "y"=> $sold[5]),
array("label"=> "July", "y"=> $sold[6]),
array("label"=> "Aug", "y"=> $sold[7]),
array("label"=> "Sep", "y"=> $sold[8]),
array("label"=> "Oct", "y"=> $sold[9]),
array("label"=> "Nov", "y"=> $sold[10]),
array("label"=> "Dec", "y"=> $sold[11])
);
