带有颜色阶梯的仪表图

Question

如何使用 highcharts 实现此目的？厌倦了使用停止：[...] 但它不会像上图那样工作。

yAxis: {
            min: 0,
            max: 100
        },
        series: [{
            name: 'customers',
            data: [{
                color: {
//
                    linearGradient: { x1: 0, y1: 0, x2: 1, y2: 0},
                    stops: [
                        [0.1, '#009a60'],
                        [0.2, '#4aa84e'],
                        [0.3, '#92b73a'],
                        [0.4, '#c6bf22'],
                        [0.5, '#edbd02'],
                        [0.6, '#ffad00'],
                        [0.7, '#ff8c00'],
                        [0.8, '#fc6114'],
                        [0.9, '#f43021'],
                        [1.0, '#ed0022']
                    ]
                },
                y:76
            }],
            dataLabels: {
                format: '<div class="prc" style="text-align:center;"><span style="font-weight:normal; font-family:Helvetica Neue, Helvetica, Arial; font-size:52px;' +
                '#333' + '">{y}</span>'
            }
        }]

获取此字符的一种方法是使用轴线和刻度线覆盖图表以创建空白。接下来，您可以添加更多点并使用渐变不支持的颜色格式设置停止点 - 例如具有 3 位数字的十六进制颜色格式 ("#rgb")。

演示：http://jsfiddle.net/bsdtsmyb/

$(function() {

  var rawData = 94,
    data = getData(rawData);

  function getData(rawData) {
    var data = [],
      start = Math.round(Math.floor(rawData / 10) * 10);
    data.push(rawData);
    for (i = start; i > 0; i -= 10) {
      data.push({
        y: i
      });
    }
    return data;
  }

  Highcharts.chart('container', {
    chart: {
      type: 'solidgauge',
      marginTop: 10
    },
    
    title: {
      text: ''
