I am using gnuplot for plotting data. I have a specific problem.

I have a data file which has titles in its first row. I want to generate separate plots for each data. Each plot should be named after its header.
Say, for instance

0 0 15 0
1 10 100 5

set terminal png
set output ".png"
plot for [i=2:4] *
using 1:i

I need the output of 1:2 as DISPLACEMENT.png, 1:3 as VELOCITY.png, etc.

Is there any way of doing it??
