discrete plot doesn't honor x and y ranges?

Using maxima 5.9.2 from Debian with gnuplot 4.0.0 

exes:[0,1,2,3,4,5,6,7];
ys:[10,5,6,9,33,7,4,1];

plot2d([discrete,exes,ys],[x,0,10],[y,0,10]);


This doesn't complain, but it doesn't set the x and y ranges
either. Especially annoying when you have outliers or singularities.

I can't figure out where in the code the ranges get set when plotting
discrete plots but it seems like it should be an easy fix?
