[英]How does HighChart jquery plugin generate the Y labels
y和y轴的起始编号和增量值在哪里? 为什么它们从5和0开始并以它们的数字递增? 我想创建以特定间隔而不是这段代码中的标签的标签。 我只是不知道在哪里更改它。

<body>
<!-- 3. Add the container -->
<div id="container" style="width: 800px; height: 400px; margin: 0 auto"></div>
</body>

尝试从参考中使用yAxis.min
和yAxis.max
: http : yAxis.max
。
例如,
max: 125
jsFiddle在这里: http : //jsfiddle.net/Wax78/
(请注意,在您的示例中, Temperature
的主要yAxis
已添加了+100。)
