Combining histograms and function plots

I am using Octave simply as a data handler and for minor calculations. I
also use it as a tool for graphical illustartion of data structures. And
it is in this resepct I have problem.

I am making histogram plots of some simulation generated data. These are
supposed to be normally distributed. I would like to combine my formal
statistical test with a visual plot of the data. But ontop of the
histogram I would also like to have the normal distribution function
drawn. It is in this resepct I am experiencing problems.

Q1: How do I plot a normal distribution function with the mean and
standard deviation of my data in Octave?

Q2: How do I plot it ontop of my histogram plots?

Hope you are able to help me. I have been going through both the
gnuplot manual and the Octave manual. I have no problem plotting in
Gnuplot. But it seems the procedure is well hitten in the Octave manual.

Thanx in advance for responding.
