Scaling line widths in a graph is not a good idea anyway.
e.g. you have a plot of a function for the range
0 < x < 1000, 0 < f(x) < 1000, and you
zoom in on an interesting range
   550 < x < 600,  200 < f(x) < 250,
then you don't want the lines to be 20 times as thick!

If you insist on scaling, you could instruct the software that
converts the plots to generate rectangles or polygons instead of
lines. (or generate the lines with the desired thickness
from scratch.)
