ExtJs integrated Echarts

This time I will bring you Echarts integrated with ExtJs. What are the precautions when using ExtJs to integrate Echarts? Here are practical cases, let’s take a look.

Since Echarts does not provide table functions, if you want to implement the above picture and the following table, you need to add a table tag yourself.

ExtJs integrates Echarts

Download the js file from the Echarts official website and create a new page through the import reference. Typesetting is done by two p placed vertically. The top is reserved for Echarts. The bottom is reserved for table tags

initPanel : function() {
 if (this.panel) {
  return
 }
 
 var panel = new Ext.Panel({
  id : 'echart',
  html :   '<p id="mainEchart" style="height:50%;border:1px solid #ccc;padding:10px;"></p>'
        + '<p id="mainTable" style="position:relative;text-align:center;padding:10px;">'
        +'<label for="mainTable"><h1>档案调用次数表</h1></label>'
        +'<table id="content-table" border="1" style="width:100%;text-align:center;">'
        + '<tr><th>月份</th><th>调用次数</th></tr>',
  buttonAlign : 'center',
  autoScroll : true,//允许滚动
  bodyStyle : 'overflow-x:hidden; overflow-y:scroll'
  //开启竖直滚动条，关闭水平滚动条
 });
 
 this.panel = panel;
 return this.panel; 
}

Echarts initialization and data loading

The official statement states that only one echarts can be generated at a time, define related styles, and query data from the background Provided to echarts

initData : function(id, personName, year) {
 this.id = id;
 var p = document.getElementById("mainEchart");
 var myChart = echarts.init(p);
 // myChart.showLoading({
 // text: "图表数据正在努力加载..."
 // });
 this.myChart = myChart;
 // 初始化数据
 var data = [];
 var yearStr = "";
 var flag = false;
 var monthData = [];
 
 var res = QueryData();//调用数据查询，涉及项目名，略
 
 for (var i = 0; i < res.json.body.length; i++) {
  var map = res.json.body[i];
  monthData.push(map.MM);//月份
  data.push(map.DYCS);//调用次数
 }
 var options = {
  arg : {
   id : this.id
  },
  noDataLoadingOption : {
   text : &#39;暂无数据&#39;,
   effect : &#39;bubble&#39;,
   effectOption : {
    effect : {
     n : 0
    }
   }
  },
  title : {
   text : personName + "的档案调用情况",
   x : &#39;west&#39;
  },
  tooltip : {
   trigger : &#39;axis&#39;
  },
  legend : {
   data : [&#39;调用次数&#39;]
  },
  toolbox : {
   show : true,
   feature : {
    mark : {
     show : true
    },
    dataView : {
    //重写dataView
    //在切换视图的时候能够以<table>的形式显示
     show : true,
     readOnly : true,
     optionToContent : function(opt) {
      var axisData = opt.xAxis[0].data;
      var series = opt.series;
      var table = '<table style="width:100%;text-align:center" border="1"><tbody><tr>'
        + '<td>时间</td>'
        + '<td>'
        + series[0].name + '</td>'
        // + '<td>'
        // + series[1].name
        // + '</td>'
        + '</tr>';
      for (var i = 0, l = axisData.length; i < l; i++) {
       table += '<tr>' + '<td>' + axisData[i]
         + '</td>' + '<td>'
         + series[0].data[i] + '</td>'
         // + '<td>' + series[1].data[i]
         // + '</td>'
         + '</tr>';
      }
      table += '</tbody></table>';
      return table;
     }
    },
    magicType : {
     show : true,
     type : ['line', 'bar']
    },
    restore : {
     show : true
    },
    saveAsImage : {
     show : true
    }
   }
  },
  calculable : true,
  xAxis : [{
     type : 'category',
     data : monthData
    }],
  yAxis : [{
     type : 'value',
     splitArea : {
      show : true
     }
    }],
  series : [{
   name : '调用次数',
   type : 'bar',
   barWidth : 35,
   data : data,
   itemStyle : {//修改柱状图的颜色并在顶部显示数值
    normal : {
     color : '#3575a8', 
     label : {
      show : true,
      position : 'top',
      formatter : '{c}'//'{b}\n{c}'
     }
    }
   }
  }]
 };
 myChart.setOption(options, true);
 myChart.on('click', function eConsole(param) {
   });
 this.tableData(personName, monthData, data)
 //表格的加载
}

Assignment of table data

The table part is a simple html assignment. There is not much to say. Just refresh the html after splicing. The code is as follows:

tableData : function(personName, monthData, data) {
 // 表格部分
 var html = '<p id="mainTable" style="position:relative;text-align:center;padding:10px;">'
   +'<label for="mainTable"><h1>'
   + personName
   + '档案调用情况表</h1></label>'
   +'<table id="content-table" border="1" style="width: 100%;text-align: center;">'
   + '<tr style="height: 30px;text-align:center;"><th>月份</th><th>调用次数</th></tr>';
 // if(monthData.length != data.length)
 // throw new Error("数据条数不对，请检查！");
 for (var i = 0; i < data.length; i++) {
  html += &#39;<tr style="height: 30px;text-align: center;">'
     +'<td id="data-month-&#39;+i+&#39;">'
     + monthData[i]
     + '</td><td id="data-value-&#39;+i+&#39;">'
     + data[i]
     + '</td></tr>'
 }
 html += '</table></p>';
 document.getElementById('mainTable').innerHTML = html;
}
