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。 // First array for purchased product $purchased= array(10, 15, 19, 0, 5, 7, 0, 0, 12, 13, 10, 1); // Second array for sold product $sold= array(7, 12, 14, 0, 3, 7, 0, 0, 10, 7, 5, 0); // Data to draw graph for purchased products $dataPoints = array( array("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"=> "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"=> $sold[11]) <html> <head> <script src="https://canvasjs.com/assets/script/canvasjs.min.js"> </script> <script> window.onload = function () { var chart = new CanvasJS.Chart("chartContainer", { animationEnabled: true, title:{ text: "Monthly Purchased and Sold Product" }, axisY: { title: "Purchased", titleFontColor: "#4F81BC", lineColor: "#4F81BC", labelFontColor: "#4F81BC", tickColor: "#4F81BC" }, axisY2: { title: "Sold", titleFontColor: "#C0504E", lineColor: "#C0504E", labelFontColor: "#C0504E", tickColor: "#C0504E" }, toolTip: { shared: true }, legend: { cursor:"pointer", itemclick: toggleDataSeries }, data: [{ type: "column", name: "Purchased", legendText: "Purchased", showInLegend: true, dataPoints:<?php echo json_encode($dataPoints, JSON_NUMERIC_CHECK); ?> }, { type: "column", name: "Sold", legendText: "Sold", axisYType: "secondary", showInLegend: true, dataPoints:<?php echo json_encode($dataPoints2, JSON_NUMERIC_CHECK); ?> }] }); chart.render(); function toggleDataSeries(e) { if (typeof(e.dataSeries.visible) === "undefined" || e.dataSeries.visible) { e.dataSeries.visible = false; } else { e.dataSeries.visible = true; } chart.render(); } } </script> </head> <body> <p id="chartContainer" style="height: 300px; width: 100%;"></p> </body> </html> （编辑：云计算网_泰州站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
