echarts 图表类型设置为time 时 ，设置x轴间隔的问题

[ahking]

series的data为：
[["2020-11-21",1],["2020-11-22",2],["2020-11-23",3],["2020-11-24",4],["2020-11-25",5]]

想设置两天显示一个数，应该怎么设置
interval: 3600, // 设置x轴时间间隔，这里的单位是什么

我发现是最新的5.0版本和原版本兼容性问题，但需要用最新版本，不知怎么设 配置项如下

option = {
tooltip: {
trigger: 'axis',
formatter: function (params, ticket, callback) {
var dataValue = params[0].value + "";
var dataArray = dataValue.split(',');
var date = new Date(dataArray[0].replace("-", "/"));

        var dataValue_peichan = params[1].value + "";
        var dataArray_peichan = dataValue_peichan.split(',');

        return (date.getMonth() + 1) + '/' + date.getDate() + '：' + dataArray[1] + '<br />配产：' + dataArray_peichan[1] + '(' + (dataArray[1] - dataArray_peichan[1]) + ')';

        //return dataArray[0] + '：' + dataArray[1];
        //console.log(params);

    }
},
grid: { top: 15, bottom: 20, left: 40, right: 20 },
xAxis: {
type: 'time',
boundaryGap: false,

axisLabel: {
formatter: function (value, index) {
// 格式化成月/日，只在第一个刻度加空格，防止挡住纵坐标刻度值
var date = new Date(value);
var texts;
if (index === 0) {
texts = [' ' + (date.getMonth() + 1), date.getDate()];
}
else {
texts = [(date.getMonth() + 1), date.getDate()];
}
console.log(texts);
//return texts;
return texts.join('/');
},

5.0之前版本能够按15天间隔，显示坐标纵线，首尾都显示横坐标标签 5.0版本按照5天间隔，不显示坐标纵线，逢一号显示数据，首尾不显示横坐标标签 5.0版本配置项该如果修改
