echarts实现向下钻取

实现一个向下钻取的效果:柱形图点击柱子则钻取,点击柱图空白返回。

line_chart1 = echarts.init(document.getElementById('lineChart1'));		
	line_option1={
		backgroundColor:'#0B2F64',
		title : {
			show:true,			
			text: '这是一个标题',
			left: 'center',
			top:10,
			textStyle : {
				color: '#09F',
				fontSize:16
			},
			subtextStyle:{
				color: '#B7E1FF',
				fontSize:12
			}
		},		
		xAxis: {
			axisLabel: {
				interval:0,
				textStyle: {
					color: '#B7E1FF',
					fontSize:12
				}
			},
			axisLine:{
				lineStyle:{
					color:'#09F'	
				}
			},
			axisTick:{
				lineStyle:{
					color:'#09F'	
				}
			},
		},
		yAxis: {			
			show:false,			
		},
		tooltip: {
			trigger: 'axis',
			textStyle: {
				color: '#FFF',
				fontSize:12
			}
		},	
		legend:{
			show:false
		},
		grid:{
			left:80,
			top:60,
			bottom:25
		},
		series: [
			{
				name: '序列1',
				type: 'bar',
				label:{
					show:true,
					position:'top',
					color:'#FFF'
				},
				itemStyle: 
				{
					normal: {
						color:function(para){
							return (para['name']==currentYear)?'#CA2E3F':color[1];
						}
					},
					emphasis: {color: color[2]}
				},
			}]
		};	
	line_chart1.on('click', function (params) {	
		params.event.event.stopPropagation();
		if(currentYear!="")
		{
			currentYear="";
			yearChanged=true;
			refreshData();
		}
		else
		{
			currentYear=params.name;
			yearChanged=true;
			refreshData();
		}		
	});		
	$('#lineChart1').on("click",function(){
		if(currentYear!="")
		{
			currentYear="";
			yearChanged=true;
			refreshData();
		}
	});	

主要是params.event.event.stopPropagation();这一句,点击柱子,需要阻止事件冒泡,这样点击柱子才不会激起背景的响应。
