Suppose, one wants to plot the value obtained from a Butterworth Filter in a graph. A log-log graph has logarithmic coordinates along both axes.

You can see that the graph is the reflection of the graph of the function y = log 4 ( x ) about the y -axis. The idea here is we use semilog or log-log graph axes so we can more easily see details for small values of y as well as large values of y.. You can see some examples of semi-logarithmic graphs in this YouTube Traffic Rank graph.
