以下是具有反转轴的样条曲线图的示例。

我们已经看到用于在Highcharts Configuration Syntax章节中绘制图表的配置。现在，我们将讨论具有反转轴的样条图的示例。

配置 (Configurations)

将图表类型配置为基于样条线。 chart.type决定图表的系列类型。这里，默认值是“line”。

配置要反转的轴。当true x axis是垂直的而y axis是水平的时 - 如果图表中存在条形系列，则相反的方向将被反转。这里，默认值为false。

图表

var chart = {
   type: 'spline',
   inverted: true
};
