1、HighCharts前端繪製圖表

使用HighCharts能夠在前端很是簡單的生成圖表html

1.1 配置語法，生成HTML頁面

<html>
<head>
<title>Highcharts 示例</title>
    <script src="/static/js/jquery/2.1.4/jquery.min.js"></script>
   <script src="/try/demo_source/highcharts.js"></script>
</head>
<body>
<div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div>
<script language="JavaScript">
$(document).ready(function() {
     
});
</script>
</body>
</html>

實例中 id 爲 container 的 div 用於包含 Highcharts 繪製的圖表前端

1.2 建立Json格式的配置文件

$('#container').highcharts(json);

1.配置標題

var title = {
  text: '月平均氣溫'   
};

2.副標題

var subtitle = {
  text: 'Source: runoob.com'
};

3.X軸

var xAxis = {
   categories: ['一月', '二月', '三月', '四月', '五月', '六月'
      ,'七月', '八月', '九月', '十月', '十一月', '十二月']
};

4.Y軸

var yAxis = {
   title: {
      text: 'Temperature (\xB0C)'
   },
   plotLines: [{
      value: 0,
      width: 1,
      color: '#808080'
   }]
};

5.提示信息

var tooltip = {
   valueSuffix: '\xB0C'
}

6.展現方式

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

7.圖表中所需數據

配置圖表要展現的數據。每一個系列是個數組，每一項在圖片中都會生成一條曲線。jquery

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: 'Berlin',
      data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 
         17.9, 14.3, 9.0, 3.9, 1.0]
   }, 
   {
      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]
   }
];

8.最後建立JSON格式的數據

var json = {};

json.title = title;
json.subtitle = subtitle;
json.xAxis = xAxis;
json.yAxis = yAxis;
json.tooltip = tooltip;
json.legend = legend;
json.series = series;
Step 4: Draw the chart
$('#container').highcharts(json);

而後調用語句畫表：$('#container').highcharts(json);json

如下完整代碼：數組

<html>
<head>
<meta charset="UTF-8" />

<script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
<script src="http://code.highcharts.com/highcharts.js"></script>
</head>
<body>
<div id="container" style="width: 550px; height: 400px; margin: 0 auto"></div>
<script language="JavaScript">
$(function() {
   var title = {
       text: '月平均氣溫'   
   };
   var credits = {
        enabled:false //表示隱藏右下角 highchart 鏈接
};
   var subtitle = {
        text: 'Source: runoob.com'
   };
   var xAxis = {
       categories: ['一月', '二月', '三月', '四月', '五月', '六月'
              ,'七月', '八月', '九月', '十月', '十一月', '十二月']
   };
   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: 'Berlin',
         data: [-0.9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6,
            17.9, 14.3, 9.0, 3.9, 1.0]
      }, 
      {
         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]
      }
   ];

   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>
</body>
</html>

2、最近工做用到的配置

function draw_chart(id,data,title) {
            // data數據格式：[[1,3],[2,4],[3,7],[4,2],[5,8],];
            var id_str = '#'+id;
            var chart_json = {
                title: {
                    text: title,
                    margin: 10,
                    style: { "fontSize": "22px" },
                },
                subtitle:{
                    text:"Pressure"
                },
                xAxis:{
                    // categories:['a', 'b', 'c', 'd', 'e']
                    title:"壓力記錄次數",
                    tickInterval: 1
                },
                credits:{
                    enabled:false
                },

                yAxis:{
                    title:{
                        text:'壓力 Pa',
                        plotLines: [{
                            value:0,
                            width:1,
                            color:'#808080'
                        }]
                    }
                },
                tooltip:{
                    formatter:function(){
                        return "第"+this.x+"次壓力記錄"+'<br/>壓力值：'+Highcharts.numberFormat(this.y,2)+'Pa';
                    }
                },
                legend:{
                    layout: 'vertical',
                    align:'right',
                    verticalAlign:'middle',
                    borderWdith:0
                },
                series:[
                    {
                        name:'當前壓力',
                        data:data
                    }
                ]
            };
            $(id_str).highcharts(chart_json)
        }
