HighCharts:可以汇总系列数据并在标题中显示吗? [英] HighCharts: Possible to summarize series data and show in title?

问题描述

我正在寻找一个答案，如果可以对HighCharts系列进行汇总并显示在标题中?我正在为该系列使用JSON数据，因此，如果数据看起来像这样:

I'm looking for an answer if it's possible to sum the HighCharts series and show it in the title? I'm using JSON data for the series, so if the data looks like this:

[0,0,0,1,1,1,2,2,2,3,3,3]

总和当然应该是:18.

The sum should of course be: 18.

我尝试询问Google，但未找到任何信息.我知道我可以在其他地方处理它，但是直接在HighCharts脚本中处理它会很好.

I've tried asking Google but I haven't found anything. I know I could handle it elsewhere but it would be nice to handle it directly inside the HighCharts script.

谢谢.

推荐答案

如何在Javascript中对其求和，然后在创建标题时使用结果?

How about summing it in Javascript and then using the result when creating the title?

var sum = 0;
for(var i in series)
    sum += i;

然后，只需设置标题:

chart = new Highcharts.Chart({
    ...

    title: {
        text: 'SUM: ' + sum
    },

    ...
)};

应该可以，对吧?
