With datafiles D1.csv

0 1 0
0 1 1
0 1 2
0 1 3
0 1 4

and D2.csv

0 10
0 20
0 30
0 40
0 50

you can plot the third column of D1.csv on the x-axis and the second column of D2.csv on the y-axis with

plot "< paste D1.csv D2.csv" u 3:5 w l

The paste command merges corresponding or subsequent lines of files giving you this output:

0 1 0   0 10
0 1 1   0 20
0 1 2   0 30
0 1 3   0 40
0 1 4   0 50

Hence, the third column of this file is the third column of D1.csv and the fifth column is the second column of D2.csv resulting in this plot:
