[[Image:loglog_x_x2_x3.png|thumb|A log-log plot of y=x (green), y=x^2 (blue), and y=x^3 (red). Note the logarithmic scale markings on each of the axes.]] AIn [[science]] and [[engineering]], a '''log-log graph''' or '''log-log plot''' is a way of visualizing data that is changing with a [[power law]]. Both horizontal and vertical axes are plotted on a [[logarithmic scale]]. All functions of the form <math>ax^b</math> form straight lines (where ''b'' determines the slope and ''a'' determines the y=1 intercept).
