Map MarkPointecharts 地图配置项内容和展示

MarkPoint设置value后,在标记出还是显示出value,只有当鼠标滑动到标记处时,才会显示value值

配置项如下
      
option = {
			    title: {
			        text: '交易量',
			        left: 'center'
			    },
			    tooltip: {
			        trigger: 'item'
			    },
			    legend: {
			        orient: 'vertical',
			        left: 'left',
			        data:['iphone3']
			    },
			    visualMap: {
			        min: 0,
			        max: 2500,
			        left: 'left',
			        top: 'bottom',
			        text: ['高','低'],           // 文本,默认为数值文本
			        calculable: true
			    },
			    toolbox: {
			        show: true,
			        orient: 'vertical',
			        left: 'right',
			        top: 'center',
			        feature: {
			            saveAsImage: {}
			        }
			    },
			    series: [
			        {
			            name: 'iphone3',
			            type: 'map',
			            map: 'cichuan',
			            roam: false,
			            label: {
			                normal: {
			                    show: true
			                },
			                emphasis: {
			                    show: true
			                }
			            },
			            data:[],
			            markPoint:{
			            	label:{normal:{show: true},emphasis:{show:true}},
			            	itemStyle:{
			            		normal:{color:'skyblue',}
			            	},
			            	data:[
			            		{name:'成都市',x: 480,y: 300,value:120}
			            	]
			            }
			        }
			    ]
			};
