Question

我是HighCharts的新用户，我试图在同一个x轴上显示2个图表），如下所示：http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/combo-multi-axes/。

但是，我收到一条错误消息：当您将一系列'xAxis或yAxis属性设置为指向不存在的轴时，会发生此错误。

错误发生在“chart1”

中

html和JAVASCRIPT代码如下：

$(function updat() {
  var url = "https://xpm4zyor39.execute-api.us-west-2.amazonaws.com/prod/entries";
  var humid = [],
    date = [],

    day=[],
    chanceOfRain=[],
    humid_final = [],
    day_final=[],
    high_final=[],
    chanceOfRain_final=[]

  $.getJSON(url, function (json) {

    $(json['Items']).each(function(i, data) {
      //Store indicator name
      
      // fill the date array
      humid.push(data.humidity);
      // fill the string data array 
      date.push(data.Date);

      high.push(data.high);
      day.push(data.Day);
      chanceOfRain.push(data.chanceOfRain);

    });

    console.log(date);
    // query send string that we need to convert into numbers
    for (var i = 0; i < humid.length; i++) {
      if (humid[i] != null) {
        humid_final.push(parseFloat(humid[i]));
        high_final.push(parseFloat(high[i]));
        day_final.push(parseFloat(day[i]));
        chanceOfRain_final.push(parseFloat(chanceOfRain[i]));

Answer 1

您正在执行以下操作：

series:[{
    yAxis:1,
  },
  {
    yAxis:2,
  }]

你需要这样做：

series:[{
    yAxis:0,
  },
  {
    yAxis:1,
  }]

问题是轴在 0 处开始索引。因此，将温度设置为轴2的索引不起作用，因为没有轴2.在演示中有3个轴，这就是为什么它适用于这些定义。
