DiscretePlot

DiscretePlot[f, {n, nmax}] generates a plot of f as a function of n for n=1, ..., nmax.

DiscretePlot[f, {n, nmin, nmax}] generates a plot when n runs from nmin to nmax.

DiscretePlot[f, {n, nmin, nmax, dn}] uses steps dn.

Examples

Plot Fibonacci numbers:

DiscretePlot[Fibonacci[n], {n, 1, 20}]

With custom styling:

DiscretePlot[n^2, {n, 1, 10}, PlotStyle -> Red, Filling -> Axis]
