下面小编就为大家带来一篇highchart数据源纵轴json内的值必须是int(详解)。小编觉得挺不错的，现在就分享给大家，也给大家做个参考。一起跟随小编过来看看吧

var users = ["0","0","0","0","0","2","0"];

这样的纵轴数据是不显示的，json里面的值必须是int类型。

必须是这样：

var users = [1,1,1,1,1,1,1];

难道不能自动转一下吗？还是我姿势不对，没有设置某个参数？

以上这篇highchart数据源纵轴json内的值必须是int(详解)就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持PHP中文网。
