I want to plot a function that is only defined on disjoint subsets of
the x-axis. It is easy enough for me to write such functions on
f(x)= 1 for [0,.5], [1.1,2], [2.3,4.1]
= undefined elsewhere
but it is not clear to me how to use gnuplot's syntax to plot the
function defined above.
Any help or suggestions would be appreciated.
Thanks in advance,
