Javascript 以编程方式更改 highcharts 中的图表标题

Programmatically change a chart title in highcharts

提问by acullen72

I have a simple column chart that I update via AJAX, and all is working fine except I cannot change the actual title of the chart when I'm updating the data.

我有一个通过 AJAX 更新的简单柱状图，除了在更新数据时无法更改图表的实际标题外，一切正常。

I've tried the obvious -

我已经尝试过显而易见的 -

chart.title="new title";
//and
chart.title.text="New title";

etc. - to no avail, and have had no success finding a solution online.

等等 - 无济于事，也没有成功在线找到解决方案。

Any help will be greatly appreciated.

任何帮助将不胜感激。

You can use setTitle(titleObj, subTitleObj)for that.

你可以用setTitle(titleObj, subTitleObj)它。

chart.setTitle({text: "New Title"});
