Matlab: making the grid in plot logarithmic

Question

I have plotted to vectors against each other, and they are already logarithmic and everything is fine with that. But now that I have my plot i want the grid to be logarithmic. I

Answer 1

If you use loglog, semilogx or semilogy instead of plot, the grid will automatically be on a log scale for the corresponding axes when using grid on.

Answer 2

If you have already plotted the axes, you can execute the following on the command line:

set(gca,'yscale','log') %# to set the y-axis to logarithmic
set(gca,'xscale','log') %# to set the x-axis to logarithmic

Have a look at axes properties to find out what else you can modify.
