[Bug-gsl] Graph adjust on the manual gsl-ref (adjusting)

[Jorge Barros de Abreu]

Hi for all.

In this link:
http://www.gnu.org/software/gsl/manual/gsl-ref.ps.gz

On the page 220 have a graph for "Bivariate Gaussian Distribution"

On the botton left have something wrong in the graph ( in numerical values on x
axis).

Thanks for your work.
