I dont understand what you want to plot? Do you have different e(a) at
different times t, that is:

e1(a) at t1
e2(a) at t2
e3(a) at t3?

If this is your case and the data looks like:

#a  e1  e2  e3  e4  ...
0    0   0   0   0
1    1   2   3   4
2    2   4   6   8
...

you could do look into splot.

if you want to create several plots of sin(a*x) with increasing a, you 
could either do

  plot a=1, plot(a*x);
  pause -1;
  plot a=2, plot(a*x);
  pause -1;
  ...

or you could save each of them into a png file and create an animation 
from there, or you could use "splot sin(y*x)"
