ECharts3实现动态数据+时间坐标轴的操作

function randomData() {
    now = new Date(+now + 1000);
    value = value + Math.random() * 21 - 10;    
    return {
        name: now.toString(),
        value: [
            now,            
            Math.round(value)
        ]
    }
}var data = [];var now = new Date();var value = Math.random() * 1000;

option = {
    title: {
        text: '动态数据 + 时间坐标轴'
    },
    tooltip: {

            var date = new Date(params.name);            
            return date.getDate() + '/' + (date.getMonth() + 1) + '/' + date.getFullYear() + ' : ' + params.value[1];
