Combine multiple series into one table

I want to combine multiple time series data into one table to export it to a .csv file.
So far, I have tried in the influx web interface, to select 5 values I want to be combined into one .csv table. They are then all shown correctly in one graph, however, when I now press export as .csv, their tables are all listed as separate blocks beneath each other.

My goal is to archive one table including all 5 values and one row of timestamp, like this:

|   _time        |  val_1 |  val_2  |  val_3 | val_4 | val_5
|   "timestamp"  |    1   |   2     |   0    | 1     | 3
|   "timestamp"  |    3   |   1     |   2    | 1     | 1
|   "timestamp"  |    2   |   1     |   0    | 1     | 2

How do I achieve this?
