Perhaps I don't understand the difference between a histogram of a set of
values and a histogram of an _indexed_ set of values but it seems to me
that the following should output the familiar "bell-shaped" distribution:
{{{
sage: J = [ZZ(n) for n in range(10^3)]
sage: A = [RR(gauss(0,1)) for n in range(10^3)]
sage: s = IndexedSequence(A,J)
sage: P = s.plot_histogram()
}}}
However, this looks pretty much the same as
{{{
sage: Q = s.plot()
}}}
Also, the following is closer to the bell curve but it still doesn't
capture what's going on: (swapping the {{{IndexedSequence}}} inputs)
{{{
sage: t = IndexedSequence(J,A)
sage: R = t.plot_histogram()
}}}
I'm just wondering if I'm missing something.
Finally, {{{finance.timeseries.TimeSeries}}} has a {{{plot_histogram}}}
method that seems to work pretty well. Maybe you can use it somehow?
Anyway, those are just my thoughts. Again, if I'm missing something I'll
be happy to take another look.
