how to line up date and time with different variables so i can scatter graph

so i have 1 system of data with 6 variables 1000 data points each variable

and very many dates and times accordingly

they all dont match properly which screws up when i graph

HOW DO I GET THEM TO MATCH EACHOTHER AND SYNC?

best way i know how is to click and drag but that takes at least 6000 times

what are the functions or keywords to use for this application?

sometimes with excel its just a word or a verb im not familiar

im learning the language

either way thanks! GODspeed
