Highcharts 2nd yaxis not scaling

Question

我可以看到2个坐标轴，但是我怎样才能缩放第二个坐标轴？我必须把代码放在哪里？我从使用json.php数据库中的数据，我不包括因为我相信我得到的结果......正如我所说的，我可以看到线........

function InitHighChart() 
{ 
$("#chart").html("Wait, Loading graph..."); 

var options = { 
    chart: { 
     renderTo: 'chart', 
     borderColor: '#a1a1a1', 
     borderWidth: 2, 
     borderRadius: 13, 
     alignTicks: false, 
     height: 550 
    }, 
    credits: { 
     enabled: false 
    }, 
    title: { 
     text: 'Ενεργός Ισχύς/Τάση', 
     x: -20 
    }, 
    xAxis: { 
     categories: [{}], 
     labels: { 
      step: 15, 
      rotation: -75 
     } 
    }, 

    yAxis: [{ // Primary yAxis 
     labels: { 
      format: '{value} MWatt', 


     }, 
     title: { 
      text: 'Ενεργός Ισχύς', 

     } 

    }, { // Secondary yAxis 
     title: { 
      text: 'Τάση', 

     }, 
     labels: { 
      format: '{value} V', 

     }, 
     opposite: true 
    }], 


    tooltip: { 
     formatter: function() { 
      var s = '<b>'+ this.x +'</b>'; 

      $.each(this.points, function(i, point) { 
       s += '<br/>'+point.series.name+': '+point.y; 
      }); 

      return s; 
     }, 
     shared: true 
    }, 
    series: [{},{}] 
}; 

$.ajax({ 
    url: "json.php", 
    data: 'show=impression', 
    type:'post', 
    dataType: "json", 
    success: function(data){ 

     options.xAxis.categories = data.datetime; 
     options.series[0].name = '...'; 
     options.series[0].data = data.ActiveData; 
     options.series[1].name = '...'; 
     options.series[1].data = data.VoltageData; 

     var chart = new Highcharts.Chart(options);   
    }, 
}); 

}

已分配第二个y轴的任何系列？这可能是问题所在。

API：http://api.highcharts.com/highcharts#series.yAxis

series: [{ 
     data: [1, 2, 3, 4, 5, 3, 5] 
    }, { 
     data: [3, 3, 5, 4, 6, 6, 3, 3, 4, 6], 
     yAxis: 1 
}]

在你的代码，你应该在

$.ajax({ 
    url: "json.php", 
    data: 'show=impression', 
    type:'post', 
    dataType: "json", 
    success: function(data){ 

     options.xAxis.categories = data.datetime; 
     options.series[0].name = '...'; 
     options.series[0].data = data.ActiveData; 
     options.series[1].name = '...'; 
     options.series[1].data = data.VoltageData; 

     options.series[1].yAxis = 1; //added line 

     var chart = new Highcharts.Chart(options);   
    }, 
});
