Add PSYM=10 to the PLOT command.

Thank you for your answer.
But I'd like to plot a histogram with rectangle shape as the "plothist"
does.
PSYM=10 doesn't work.

Or you could use bar_plot with /rotate. There might be some other
keywords that would need to be set, and it's not as painless as the
regular plot with psym=10, but it'll work

Uh, well, like this:
h = histogram(dist(256),omin=minval, omax=maxval)
plot, h, scale_vector(findgen(n_elements(h)), minval, maxval)
You can find SCALE_VECTOR here, or you can produce
your own dependent vector in whatever way you like:
