Highcharts

1. 折線圖每一個點顯示tooltip 的備註信息不一樣

<div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div>
<script language="JavaScript">
$(document).ready(function() {
   var rdate ={ 'Jan':'測試一', 'Feb':'測試二', 'Mar':'測試三', 'Apr':'測試四', 'May':'測試五', 'Jun':'測試六',
         'Jul':'測試七', 'Aug':'測試八', 'Sep':'測試九', 'Oct':'測試十', 'Nov':'測試十一', 'Dec':'測試十二'};
   var title = {
      text: '城市平均氣溫'   
   };
   var subtitle = {
      text: 'Source: runoob.com'
   };
   var xAxis = {
      categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
         'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
   };
   var yAxis = {
      title: {
         text: 'Temperature (\xB0C)'
      },
      plotLines: [{
         value: 0,

   var tooltip = {
	  shared: true,
       formatter: function() {
		     console.log(this);
		     console.log(rdate[this.x]);
              return this.y+'<br>'+rdate[this.x] ;
       }
   }

   var legend = {
      layout: 'vertical',
      align: 'right',
      verticalAlign: 'middle',
      borderWidth: 0
   };

   var series =  [
      {
         name: 'Tokyo',
         data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2,
            26.5, 23.3, 18.3, 13.9, 9.6]
      }
   ];

   var json = {};

   json.title = title;
   json.subtitle = subtitle;
   json.xAxis = xAxis;
   json.yAxis = yAxis;
   json.tooltip = tooltip;
   json.legend = legend;
   json.series = series;

   $('#container').highcharts(json);
});
</script>

<div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div>
<script language="JavaScript">
$(document).ready(function() {
   var rdate =[
            {'key': 'Jan','value':'測試一'},
            {'key':'Feb','value':'測試二'},
            {'key':'Mar','value':'測試三'},
            {'key':'Apr','value':'測試四'},
            {'key':'May','value':'測試五'},
            {'key':'Jun','value':'測試六'},
            {'key':'Jul','value':'測試七'},
            {'key': 'Aug','value':'測試八'}, 
            {'key':'Sep','value':'測試九'},
            {'key':'Oct','value':'測試十'}, 
            {'key':'Nov','value':'測試十一'},
            {'key':'Dec','value':'測試十二'}];
   var title = {
      text: '城市平均氣溫'   
   };
   var subtitle = {
      text: 'Source: runoob.com'
   };
   var xAxis = {
      categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
         'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
   };
   var yAxis = {
      title: {
         text: 'Temperature (\xB0C)'
      },
      plotLines: [{
         value: 0,
         width: 1,
         color: '#808080'
      }]
   };   

   var tooltip = {
	  shared: true,
       formatter: function() {

               var rValue = '';
               for (var i=0;i<rdate.length;i++){
                   if(rdate[i].key == this.x){
                          rValue = rdate[i].value;
                    }

   $('#container').highcharts(json);
});
</script>

3. 折線圖點擊事件

<div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div>
<script language="JavaScript">
$(document).ready(function() {
   var title = {
      text: '城市平均氣溫'   
   };
   var subtitle = {
      text: 'Source: runoob.com'
   };
   var xAxis = {
      categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
         'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
   };
   var yAxis = {
      title: {
         text: 'Temperature (\xB0C)'
      },
      plotLines: [{
         value: 0,
         width: 1,
         color: '#808080'
      }]
   };   

   var tooltip = {
      valueSuffix: '\xB0C'
   }

   var legend = {
      layout: 'vertical',
      align: 'right',
      verticalAlign: 'middle',
      borderWidth: 0
   };

   var series =  [
      {
         name: 'Tokyo',
         data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2,
            26.5, 23.3, 18.3, 13.9, 9.6]
      }, 
      {
         name: 'New York',
         data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8,
            24.1, 20.1, 14.1, 8.6, 2.5]
      },
      {
         name: 'London',
         data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 
            16.6, 14.2, 10.3, 6.6, 4.8]
      }
   ];

   /* 單擊事件 */
   var plotOptions = {
		series : {
			cursor: 'pointer', 
			events : {
				click: function(event) {
					console.log(event);
					console.log(this);
					alert("點擊了："+this.name+" |"+event.point.category)
				}
			}
		}
	};

   var json = {};

   json.title = title;
   json.subtitle = subtitle;
   json.xAxis = xAxis;
   json.yAxis = yAxis;
   json.tooltip = tooltip;
   json.legend = legend;
   json.series = series;
   json.plotOptions = plotOptions;

   $('#container').highcharts(json);
});
</script>

4. 添加折線圖縮放

var chart = {
	  zoomType: 'x'
   };
