ECharts,缩写来自Enterprise Charts,商业级数据图表,一个纯Javascript的图表库,可以流畅的运行在PC和移动设备上,兼容当前绝大部分浏览器(IE6/7/8/9/10/11,chrome,firefox,Safari等),底层依赖轻量级的Canvas类库ZRender,提供直观,生动,可交互,可高度个性化定制的数据可视化图表。创新的拖拽重计算、数据视图、值域漫游等特性大大增强了用户体验,赋予了用户对数据进行挖掘、整合的能力。

支持折线图(区域图)、柱状图(条状图)、散点图(气泡图)、K线图、饼图(环形图)、雷达图(填充雷达图)、和弦图、力导向布局图、地图、仪表盘、漏斗图、事件河流图等12类图表,同时提供标题,详情气泡、图例、值域、数据区域、时间轴、工具箱等7个可交互组件,支持多图表、组件的联动和混搭展现。

通用基本创建可参照echarts文档

 

这里只讲一下map(地图)的一些用法总结:

   1、常见地图后(中国地图或者其他),我们可以发现地图的默认背景颜色是灰色的,如果需要自定义那么要设置:itemStyle=>normal=>color: ‘自定义的颜色值‘,

   2、如果使用的是中国地图,需要设置每个省份的颜色,在文档中是不提供接口的,也就是没有办法自定义,这时我们可以调用“值域控件”来实现,根据每个省份的不同的值,来定义颜色;设置如下:

 

1)设置省份值;

series : [
       {
           name: ‘随机数据‘,
           type: ‘map‘,
           mapType: ‘china‘,
           selectedMode : ‘single‘,
           itemStyle:{
               normal:{
label:{show:true},
borderWidth:1,//省份的边框宽度
                   borderColor:‘#f60‘,//省份的边框颜色
           color:‘#ece2df‘//地图背景颜色
//areaStyle:{color:‘#f60‘}//设置地图颜色
},
               emphasis:{label:{show:true}}
           },
           data:[
               {name: ‘北京‘, selected:false,value:1},
               {name: ‘天津‘, selected:false,value:2},
               {name: ‘上海‘, selected:false,value:3},
               {name: ‘重庆‘, selected:false,value:4},
               {name: ‘河北‘, selected:false,value:5},
               {name: ‘河南‘, selected:false,value:6},
               {name: ‘云南‘, selected:false,value:7},
               {name: ‘辽宁‘, selected:false,value:8},
               {name: ‘黑龙江‘, selected:false,value:9},
               {name: ‘湖南‘, selected:false,value:10},
               {name: ‘安徽‘, selected:false,value:11},
               {name: ‘山东‘, selected:false,value:12},
               {name: ‘新疆‘, selected:false,value:13},
               {name: ‘江苏‘, selected:false,value:14},
               {name: ‘浙江‘, selected:false,value:15},
               {name: ‘江西‘, selected:false,value:16},
               {name: ‘湖北‘, selected:false,value:17},
               {name: ‘广西‘, selected:false,value:18},
               {name: ‘甘肃‘, selected:false,value:19},
               {name: ‘山西‘, selected:false,value:20},
               {name: ‘内蒙古‘, selected:false,value:21},
               {name: ‘陕西‘, selected:false,value:22},
               {name: ‘吉林‘, selected:false,value:23},
               {name: ‘福建‘, selected:false,value:24},
               {name: ‘贵州‘, selected:false,value:25},
               {name: ‘广东‘, selected:false,value:26},
               {name: ‘青海‘, selected:false,value:27},
               {name: ‘西藏‘, selected:false,value:28},
               {name: ‘四川‘, selected:false,value:29},
               {name: ‘宁夏‘, selected:false,value:30},
               {name: ‘海南‘, selected:false,value:31},
               {name: ‘台湾‘, selected:false,value:32},
               {name: ‘香港‘, selected:false,value:33},
               {name: ‘澳门‘, selected:false,value:34}
           ]//各省地图颜色数据依赖value
       }
   ]

  2)、设置各省份的颜色,这里会显示出一个图例;

dataRange: {
       x: ‘-1000px‘,//图例横轴位置
       y: ‘-1000px‘,//图例纵轴位置
       splitList: [
           {start:1, end:1, label: ‘北京‘, color: ‘#cfc5de‘},
{start:2, end:2, label: ‘天津‘, color: ‘#f1ebd1‘},
{start:3, end:3, label: ‘上海‘, color: ‘#feffdb‘},
{start:4, end:4, label: ‘重庆‘, color: ‘#e0cee4‘},
{start:5, end:5, label: ‘河北‘, color: ‘#fde8cd‘},
{start:6, end:6, label: ‘河南‘, color: ‘#e4f1d7‘},
{start:7, end:7, label: ‘云南‘, color: ‘#fffed7‘},
{start:8, end:8, label: ‘辽宁‘, color: ‘#e4f1d7‘},
{start:9, end:9, label: ‘黑龙江‘, color: ‘#e4f1d7‘},
{start:10, end:10, label: ‘湖南‘, color: ‘#fffed7‘},
{start:11, end:11, label: ‘安徽‘, color: ‘#fffed8‘},
{start:12, end:12, label: ‘山东‘, color: ‘#dccee7‘},
{start:13, end:13, label: ‘新疆‘, color: ‘#fffed7‘},
{start:14, end:14, label: ‘江苏‘, color: ‘#fce8cd‘},
{start:15, end:15, label: ‘浙江‘, color: ‘#ddceeb‘},
{start:16, end:16, label: ‘江西‘, color: ‘#e4f1d3‘},
{start:17, end:17, label: ‘湖北‘, color: ‘#fde8cd‘},
{start:18, end:18, label: ‘广西‘, color: ‘#fde8cd‘},
{start:19, end:19, label: ‘甘肃‘, color: ‘#fde8cd‘},
{start:20, end:20, label: ‘山西‘, color: ‘#fffdd6‘},
{start:21, end:21, label: ‘内蒙古‘, color: ‘#ddcfe6‘},
{start:22, end:22, label: ‘陕西‘, color: ‘#fad8e9‘},
{start:23, end:23, label: ‘吉林‘, color: ‘#fce8cd‘},
{start:24, end:24, label: ‘福建‘, color: ‘#fad8e8‘},
{start:25, end:25, label: ‘贵州‘, color: ‘#fad8e8‘},
{start:26, end:26, label: ‘广东‘, color: ‘#ddcfe8‘},
{start:27, end:27, label: ‘青海‘, color: ‘#fad8e9‘},
{start:28, end:28, label: ‘西藏‘, color: ‘#ddcfe6‘},
{start:29, end:29, label: ‘四川‘, color: ‘#e4f1d5‘},
{start:30, end:30, label: ‘宁夏‘, color: ‘#fefcd5‘},
{start:31, end:31, label: ‘海南‘, color: ‘#fad8e9‘},
{start:32, end:32, label: ‘台湾‘, color: ‘#fce8cd‘},
{start:33, end:33, label: ‘香港‘, color: ‘#dc9bbb‘},
{start:34, end:34, label: ‘澳门‘, color: ‘#e0f7cc‘},

       ]
   },//各省地图颜色;start:值域开始值;end:值域结束值;label:图例名称;color:自定义颜色值;
