echart.setOption({
	series: [
		{
			type: 'pie',
			data: [
				{ value: 335, name: '教师', itemStyle: { color: '#204570' } },
				{ value: 234, name: '学生', itemStyle: { color: '#204570' } },

});
echart.dispatchAction({
	type: 'highlight',
	seriesIndex: 1,

echart.on('mouseover', function(e) {
	console.log(e);
	echart.dispatchAction({
		type: "highlight",
		seriesIndex: 0,
		dataIndex:1
	});
