基于canvasJS在PHP中制作动态图表
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:
"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]) ); //Datatodrawgraphforsoldproducts $dataPoints2=array( array("label"=>"Jan","y"=>$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]) ); ?>
