Highcharts 测量图
以下实例演示了测量图。
我们在前面的章节已经了解了 Highcharts 基本配置语法。接下来让我们来看下其他的配置。
配置
chart.type 配置
配置 chart 的 type 为 'gauge' 。chart.type 描述了图表类型。默认值为 "line"。
var chart = { type: 'guage' };
pane 配置
pane 只适用在极坐标图和角度测量仪。此可配置对象持有组合x轴和y周的常规选项。每个x轴和y轴都可以通过索引关联到窗格中。
var pane = { startAngle: -150, // x轴或测量轴的开始度数，以度数的方式给出。0是北 endAngle: 150 //x轴极坐标或角度轴的最终度数，以度数的方式给出。0是北 };

以上实例输出结果为：
