Highcharts 測量圖 · W3School Highcharts 教程

# Highcharts 測量圖以下實例演示了測量圖。我們在前面的章節已經了解了 Highcharts 基本配置語法。接下來讓我們來看下其他的配置。 ## 配置 ### chart.type 配置配置 chart 的 type 為 'gauge' 。chart.type 描述了圖表類型。默認值為 "line"。 ``` var chart = { type: 'guage' }; ``` ### pane 配置 pane 只適用在極坐標圖和角度測量儀。此可配置對象持有組合x軸和y周的常規選項。每個x軸和y軸都可以通過索引關聯到窗格中。 ``` var pane = { startAngle: -150, // x軸或測量軸的開始度數，以度數的方式給出。0是北 endAngle: 150 //x軸極坐標或角度軸的最終度數，以度數的方式給出。0是北 }; ``` ### 實例文件名：highcharts_guage_angular.htm ``` <html> <head> <title>Highcharts 教程 | 菜鳥教程(runoob.com)</title> <script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script> <script src="/try/demo_source/highcharts.js"></script> <script src="/try/demo_source/highcharts-more.js"></script> </head> <body> <div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div> <script language="JavaScript"> $(document).ready(function() { var chart = { type: 'gauge', plotBackgroundColor: null, plotBackgroundImage: null, plotBorderWidth: 0, plotShadow: false }; var title = { text: '車速表' }; var pane = { startAngle: -150, endAngle: 150, background: [{ backgroundColor: { linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 }, stops: [ [0, '#FFF'], [1, '#333'] ] }, borderWidth: 0, outerRadius: '109%' }, { backgroundColor: { linearGradient: { x1: 0, y1: 0, x2: 0, y2: 1 }, stops: [ [0, '#333'], [1, '#FFF'] ] }, borderWidth: 1, outerRadius: '107%' }, { // default background }, { backgroundColor: '#DDD', borderWidth: 0, outerRadius: '105%', innerRadius: '103%' }] }; // the value axis var yAxis = { min: 0, max: 200, minorTickInterval: 'auto', minorTickWidth: 1, minorTickLength: 10, minorTickPosition: 'inside', minorTickColor: '#666', tickPixelInterval: 30, tickWidth: 2, tickPosition: 'inside', tickLength: 10, tickColor: '#666', labels: { step: 2, rotation: 'auto' }, title: { text: 'km/h' }, plotBands: [{ from: 0, to: 120, color: '#55BF3B' // green }, { from: 120, to: 160, color: '#DDDF0D' // yellow }, { from: 160, to: 200, color: '#DF5353' // red }] }; var series= [{ name: 'Speed', data: [80], tooltip: { valueSuffix: ' km/h' } }]; var json = {}; json.chart = chart; json.title = title; json.pane = pane; json.yAxis = yAxis; json.series = series; // Add some life var chartFunction = function (chart) { if (!chart.renderer.forExport) { setInterval(function () { var point = chart.series[0].points[0], newVal, inc = Math.round((Math.random() - 0.5) * 20); newVal = point.y + inc; if (newVal < 0 || newVal > 200) { newVal = point.y - inc; } point.update(newVal); }, 3000); } }; $('#container').highcharts(json,chartFunction); }); </script> </body> </html> ``` 以上實例輸出結果為： ![](https://box.kancloud.cn/2015-12-29_5682517fee3da.png)
