highcharts工具提示格式数亿亿美元 [英] highcharts tooltip format millions billions

问题描述

我想在高线图折线图上显示几个大数字.

I want to display couple of points on a highcharts line chart which are big numbers.

例如100,000，10,000,000，1,000,000,000

e.g. 100,000, 10,000,000, 1,000,000,000

当我显示这些数字时，y轴会自动将数字格式化为100 k，10 M，1,000 M等，但工具提示仍会显示实际的大数字.

When I display these, the y axis automatically formats the number into 100 k, 10 M, 1,000 M etc but the tooltip still shows the actual big number.

是否可以在工具提示中将1,000,000,000显示为1 B或1000M.

Is it possible to show 1,000,000,000 as 1 B or 1000 M in the tooltip itself.

示例- http://jsfiddle.net/ynCKW/1/

我正在尝试使用numberFormat函数，但我认为它不是正确的函数.

I am trying to play with the numberFormat function but I dont think its the right function.

Highcharts.numberFormat(this.y,0)

我是否必须编写一个自定义函数来在工具提示中进行这种格式化?

Do I have to write a custom function which would do this formatting in the tooltip?

推荐答案

您可以使用与Highcharts核心中实现的逻辑相同的逻辑:

You can use the same logic as implemented in Highcharts core:

    tooltip: {
        formatter: function () {
            var ret = '',
                multi,
                axis = this.series.yAxis,
                numericSymbols = ['k', 'M', 'G', 'T', 'P', 'E'],
                i = numericSymbols.length;
            while (i-- && ret === '') {
                multi = Math.pow(1000, i + 1);
                if (axis.tickInterval >= multi && numericSymbols[i] !== null) {
                    ret = Highcharts.numberFormat(this.y / multi, -1) + numericSymbols[i];
                }
            }
            return ret;
        }
    },

Highcharts v6的

我们可以调用内置方法，该方法应该更易于维护: http://jsfiddle .net/BlackLabel/ynCKW/104/

We can call build-in method, which should be easier to maintain: http://jsfiddle.net/BlackLabel/ynCKW/104/

    tooltip: {
        valueSuffix: '',
        formatter: function () {
            var axis = this.series.yAxis;

            return axis.defaultLabelFormatter.call({
                axis: axis,
                value: this.y
            });
        }
    },
