Rounding results in highcharts jquery script
提问by Robert E
I know this is a bit out there... but gonna ask anyways. I'm using highcharts jquery script (http://www.highcharts.com/) to generate a pie chart. I am trying to round off the number results in the pie chart and cannot find any documentation to do so. I'm stuck!
我知道这有点过时了……但还是要问一下。我正在使用 highcharts jquery 脚本 (http://www.highcharts.com/) 生成饼图。我试图四舍五入饼图中的数字结果，但找不到任何文档来这样做。我被卡住了！
My data looks something like this:
我的数据看起来像这样：
data: [
['Equity', 3],
['Cash', 6]
]
And the pie chart outputs: 33.333333333333 and 66.666666666666
饼图输出： 33.333333333333 和 66.666666666666
I'd rather get the results rounded up and down respectively so it reads and shows 33 and 64. Does anyoone know how this can be set up in highcharts?
我宁愿将结果分别向上和向下取整，以便读取并显示 33 和 64。有人知道如何在 highcharts 中设置它吗？

In in the tooltip option in the configuration object use Math.round() in the formatter function.
在配置对象的工具提示选项中，在格式化程序函数中使用 Math.round()。
tooltip: {
formatter: function() {
return '<b>'+ this.point.name +'</b>: '+ Math.round(this.percentage) +' %';
}
},

Instead of use formatteryou can set yDecimalsas 2:
相反，使用formatter你可以设置yDecimals为2：
tooltip: {
yDecimals: 2
}
yDecimals: NumberHow many decimals to show in each series' y value. This is overridable in each series' tooltip options object. The default is to preserve all decimals.
