You can play with the axis properties of a plot, especially xtick and xticklabels. The first one lets you set your own location of tick-marks, the second lets you set arbitrary labels for those ticks. Example:

x = logspace(0, log10(64), 100);
plot(x, log2(x)) % plot something
set(gca, 'xtick', (2.^(0:6))) % set ticks at 1,2,4,8,...
set(gca, 'xscale', 'log') % scale x-axis logarithmic
