df -k output

Hi:

I=B4m looking for any way to create a df -k unix output using gnuplot:

for this df -k command=B4s output:

/usr  98%
/var  75%
/tmp  33%
/opt  50%

I need a graphical representation like this:

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D  98%
/usr

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D 75%
/var

=3D=3D=3D=3D=3D=3D 33%
/tmp

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D 50%
/opt

How could I create a graphics using gnuplot ?

Thank you.
