Highcharts 對數圖表 · W3School Highcharts 教程

# Highcharts 對數圖表以下實例演示了對數圖表。我們在前面的章節已經了解了 Highcharts 配置語法。接下來讓我們來看下如何配置。 ## 配置配置 yAxis.type 為 'logarithmic'。它定義了 x 軸類型。可選值有 "linear", "logarithmic", "datetime" 或 "category"。默認值為linear。 ``` yAxis var yAxis = { type: 'logarithmic', minorTickInterval: 0.1 }; ``` ### 實例文件名：highcharts_line_logarithmic.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> </head> <body> <div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div> <script language="JavaScript"> $(document).ready(function() { var title = { text: '對數實例(runoob.com)' }; var xAxis = { tickInterval: 1 }; var yAxis = { type: 'logarithmic', minorTickInterval: 0.1 }; var tooltip = { headerFormat: '<b>{series.name}</b><br>', pointFormat: 'x = {point.x}, y = {point.y}' }; var plotOptions = { spline: { marker: { enabled: true } } }; var series= [{ name: 'data', data: [1, 2, 4, 8, 16, 32, 64, 128, 256, 512], pointStart: 1 } ]; var json = {}; json.title = title; json.tooltip = tooltip; json.xAxis = xAxis; json.yAxis = yAxis; json.series = series; json.plotOptions = plotOptions; $('#container').highcharts(json); }); </script> </body> </html> ``` 以上實例輸出結果為： ![](https://box.kancloud.cn/2015-12-29_568251747f237.png)
