Population pyramids

[Alex van der Spek]

I can't find how to plot a histogram with horizontal boxes. The script below
does fine for a population pyramid, printing it on paper only requires to
rotate the paper by -90 degrees! It appears as if horizontal boxes are not
possible?
Thanks in advance,

That is correct. Horizontal boxes are not possible.
Gnuplot always plots the independent variable on the horizontal and the
dependent variable on the vertical.

Thanks Ethan and Wouter. Confirms what I thought and had set out to do.
