Can't plot a function

edit

The command plot samples 200 points in the specified interval.

For the combinatorial function in the question, only integer values matter.

The corresponding plotting function is list_plot.

sage: g = lambda x: binomial(3, x) * binomial(3, 2 - x) / binomial(6, 2)
sage: glist = [g(x) for x in range(3)]
sage: gplot = list_plot(glist, ymin=0, size=30)
sage: gplot.show()
