Steps to Reproduce

一年的数据，若干条线，每条线的时间点都不一样，比如第一条可能只要1月到12月的某几天有数据，每条都不一样，常规下是正常连在一起的，放大后，因为X轴对应的时间点没有数据，所以整个图例是空白的，或者只有2个点，有没有什么Api可以连接空白的

Steps to Reproduce

One year’s data, several lines, and the time point of each line is different. For example, the first line may only have data for a few days from January to December, and each line is different. Normally, it is connected together normally. Yes, after zooming in, because there is no data at the time point corresponding to the X axis, the entire legend is blank, or there are only 2 points, is there any API that can be connected to the blank

不是的，是用dataZoom放大后，对应x轴没有数据的没有线，空白的，应为是一年的数据，所以如果没有api的话需要补值，一年的值都要补

series:[
           {
               name:"a",
               data:[
                   {
                       value:['2021-01-01 00:00','10000']
                   },
                   {
                       value:['2021-02-03 00:00','9999']
                   },
                   {
                       value:['2021-06-03 00:00','9999']
                   },
                   {
                       value:['2021-09-03 00:00','9999']
                   }
               ]
           },
           {
               name:"b",
               data:[
                   {
                       value:['2021-01-01 00:00','10000']
                   },
                   {
                       value:['2021-02-01 00:00','9999']
                   },
                   {
                       value:['2021-03-03 00:00','9999']
                   },
                   {
                       value:['2021-12-03 00:00','9999']
                   }
               ]
           }
       ]

这种的结构，如果我使用datazoom缩放到10月到12月，也就是没有数据的这个时间，会显示空白
