hHist = histfit( rand(100,1), 3, 'normal' )
hHist(1).YData
will give you the numbers if you extract the values from what that gives you.
hHist should be a vector of two graphics handles, the first is a patch that renders the bar chart (the 2nd is a Line object).
Because it is a patch object you get the YData out in slightly less obvious format than you would for a line plot, but the values you want are obvious from its result.
