For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf, Inf). loglog (X,Y) plots x - and y -coordinates using a base 10 logarithmic scale on the x -axis and the y -axis. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.

Use this code to produce figure 8.5a and 8.5b based on
% data x = -3:0.1:3; y = sign(x).*10.^abs(x); % scaling function scale = @(x) sign(x).*log10(abs(x)); N = 7; % number of ticks desired % picking of adequate values for the labels TickMask = linspace(1,numel(y),N); YTickLabels = y(TickMask); % scale labels and plotdata, remove NaN ->inconsistency, do you really want that? loglog (X,Y) plots x - and y -coordinates using a base 10 logarithmic scale on the x -axis and the y -axis.

For real values of X in the interval (0, Inf), log10 returns real values in the interval (-Inf, Inf).
Is there a command for a log10(x)log10(y) plot? Best Answer. loglog is to the base of 10 (just see the axis scale). Related Question. How to plot a diagonal line on a log-log
If you use xlim([5000 8000]) the plots are superficially the same because the range of x-values is so limited the difference in scaling between the log and linear axes isn't much at all. Widening the scale as I did show how the log axis is foreshortened in the upper half significantly, IF there's a wide-enough range for the log to make any difference. 2.
