Echarts的应用实践

Echarts官网：https://echarts.apache.org/

echarts是百度推出的，使用JavaScript实现的开源可视化库，可以提供直观、可定制化的数据可视化图表，包括折线图、柱状图、散点图、地图和饼图等

在js里面的写法：

self.Chart3=echarts.init(self.$el.find('#mo_chart3')[0]);
self.Chart3.setOption(self.get_chart3_option(self.render_data.block3));

self.Chart5=echarts.init(self.$el.find('#mo_chart5')[0]);
self.Chart5.setOption(self.get_chart5_option());

get_chart3_option:function(block){
             return{
                  tooltip:{
                     trigger:'item',
                     formatter:"{a} <br/> {b}: {c} (%)"
                  },
                  legend:{
                      orient: 'vertical',
                      left: 'left',
                      data:['报价','报价已发送','销售订单']
                  },
                  toolbox:{
                      show:true,
                      feature:{
                            dataView:{show:true,readOnly:false},
                            saveAsImage:{show:true},
                      }
                  },
                  series: [
                    {
                        name: '访问来源',

                            {value: block['type_num']['B'], name: '报价已发送'},
                            {value: block['type_num']['C'], name: '销售订单'}
                        ],
                        itemStyle: {
                            emphasis: {

                            }
                        }
                    }
                ]
             };
         },

         get_chart5_option:function(block){
             return {

                            curveness: 0
                        }
                    }
                ]
            };
         },

在xml里写法

<div class="panel-body">
   <div id="mo_chart3" style="width:100%;height:300px"/>

 </div>

导入echarts包：

<script type="text/javascript" src="/demo/static/src/js/echarts.min.js"/>

最后形成的效果图：
