LogLogPlot

LogLogPlot[f, {x, xmin, xmax}] generates a log-log plot of f as a function of x from xmin to xmax.

LogLogPlot[{f1, f2, ...}, {x, xmin, xmax}] plots several functions f_i.

Examples

Log-log plot:

LogLogPlot[x^2, {x, 1, 100}]

Multiple functions:

LogLogPlot[{x, x^2, x^3}, {x, 1, 1000}]
