我正在使用Highcharts生成折线图。

我有一个问题numberFormat

var test = 15975000;
numberFormat(test, 0,',','.');

结果是:15.975.000

但我想转变10001k100000100k10000001m喜欢这个。我该如何处理这个问题?

numberFormat 在 Highcharts 对象中可用。

Highcharts.numberFormat(test, 0,',','.');

示例http://jsfiddle.net/DaBYc/1/

yAxis: {
        labels: {
            formatter: function () {
                return Highcharts.numberFormat(this.value,0);
            }
        }
    },

编写您自己的格式化程序(参见此示例)。

formatter: function() {
  result = this.value;
  if (this.value > 1000000) { result = Math.floor(this.value / 1000000) + "M" }
  else if (this.value > 1000) { result = Math.floor(this.value / 1000) + "k" }
  return result;
}

你只需要这样做:

                labels: {
                formatter: function() {
                     return abbrNum(this.value,2); // Need to call the function for each value shown by the chart
                }
            },

这是用于转换要插入到 javascript 上的数据的函数:

    function abbrNum(number, decPlaces) {
    // 2 decimal places => 100, 3 => 1000, etc
    decPlaces = Math.pow(10,decPlaces);

    // Enumerate number abbreviations
    var abbrev = [ "k", "m", "b", "t" ];

    // Go through the array backwards, so we do the largest first
    for (var i=abbrev.length-1; i>=0; i--) {

        // Convert array index to "1000", "1000000", etc
        var size = Math.pow(10,(i+1)*3);

        // If the number is bigger or equal do the abbreviation
        if(size <= number) {
             // Here, we multiply by decPlaces, round, and then divide by decPlaces.
             // This gives us nice rounding to a particular decimal place.
             number = Math.round(number*decPlaces/size)/decPlaces;

             // Handle special case where we round up to the next abbreviation
             if((number == 1000) && (i < abbrev.length - 1)) {
                 number = 1;
                 i++;
             }

             // Add the letter for the abbreviation
             number += abbrev[i];

             // We are done... stop
             break;
        }
    }

    return number;
}

希望这有效=)

如果您想格式化 Highstock 图表:

   tooltip: {
        pointFormatter: function() {
          var result = this.y;
        let header = '<table>';
        let body = '<tr><td style = "color: ' + this.series.color + ';padding:0">'
          + this.series.name + ': </td><td style = "padding:0"><b>';
        if (result > 1000000) {
          result = Math.floor(result / 1000000) + "M"
        }
        else if (result > 1000) {
          result = Math.floor(result / 1000) + "k"
        }
        return header + body + result + '</b></td></tr></table>';
        }
    },

我很难找到一种在不妨碍数据分组功能或日期的情况下添加百万和数千的方法。
