Highcharts 異步加載數據曲線圖表 · W3School Highcharts 教程

# Highcharts 異步加載數據曲線圖表以下實例演示了異步加載數據曲線圖表。這邊我們通過 jQuery.getJSON() 方法從異步加載 csv 文件：我們在前面的章節已經了解了 Highcharts 配置語法。接下來讓我們來看個完整實例： ## 導入 data.js 文件異步加載數據需要引入以下js 文件： ``` <script src="http://code.highcharts.com/modules/data.js"></script> ``` ## 配置 ### X 軸以每周為間隔設置 X 軸： ``` var xAxis = { tickInterval: 7 * 24 * 3600 * 1000, // 一周 tickWidth: 0, gridLineWidth: 1, labels: { align: 'left', x: 3, y: -3 } }; ``` ### Y 軸以每周為間隔設置 Y 軸：配置兩個 Y 軸： ``` var yAxis = [{ // 左邊 Y 軸 title: { text: null }, labels: { align: 'left', x: 3, y: 16, format: '{value:.,0f}' }, showFirstLabel: false },{ // 右邊 Y 軸 linkedTo: 0, gridLineWidth: 0, opposite: true, title: { text: null }, labels: { align: 'right', x: -3, y: 16, format: '{value:.,0f}' }, showFirstLabel: false } ]; ``` ### plotOptions plotOptions用于設置圖表中的數據點相關屬性。 ``` var plotOptions = { series: { cursor: 'pointer', point: { events: { click: function (e) { hs.htmlExpand(null, { pageOrigin: { x: e.pageX || e.clientX, y: e.pageY || e.clientY }, headingText: this.series.name, maincontentText: Highcharts.dateFormat('%A, %b %e, %Y', this.x) + ':<br/> ' + this.y + ' visits', width: 200 }); } } }, marker: { lineWidth: 1 } } } ``` ### 實例文件名：highcharts_line_ajax.html ``` <html> <head> <title>Highcharts Tutorial</title> <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="http://code.highcharts.com/highcharts-more.js"></script> <script src="http://code.highcharts.com/modules/data.js"></script> </head> <body> <div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div> <script language="JavaScript"> $(document).ready(function() { var title = { text: 'Daily visits at www.highcharts.com' }; var subtitle = { text: 'Source: Google Analytics' }; var xAxis = { tickInterval: 7 * 24 * 3600 * 1000, // 一周 tickWidth: 0, gridLineWidth: 1, labels: { align: 'left', x: 3, y: -3 } }; var yAxis = [{ // 左邊 y 軸 title: { text: null }, labels: { align: 'left', x: 3, y: 16, format: '{value:.,0f}' }, showFirstLabel: false },{ // 右邊 y 軸 linkedTo: 0, gridLineWidth: 0, opposite: true, title: { text: null }, labels: { align: 'right', x: -3, y: 16, format: '{value:.,0f}' }, showFirstLabel: false } ]; var tooltip = { shared: true, crosshairs: true } var legend = { align: 'left', verticalAlign: 'top', y: 20, floating: true, borderWidth: 0 }; var plotOptions = { series: { cursor: 'pointer', point: { events: { click: function (e) { hs.htmlExpand(null, { pageOrigin: { x: e.pageX || e.clientX, y: e.pageY || e.clientY }, headingText: this.series.name, maincontentText: Highcharts.dateFormat('%A, %b %e, %Y', this.x) + ':<br/> ' + this.y + ' visits', width: 200 }); } } }, marker: { lineWidth: 1 } } } var series = [{ name: 'All visits', lineWidth: 4, marker: { radius: 4 } }, { name: 'New visitors' }] var json = {}; json.title = title; json.subtitle = subtitle; json.xAxis = xAxis; json.yAxis = yAxis; json.tooltip = tooltip; json.legend = legend; json.series = series; json.plotOptions = plotOptions; $.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=analytics.csv&callback=?', function (csv) { var data = { csv: csv }; json.data = data; $('#container').highcharts(json); }); }); </script> </body> </html> ``` 以上實例輸出結果為： ![](https://box.kancloud.cn/2015-12-29_568251723c258.png)
