MATLAB: How to scale an axis on a plot in powers of 10

axis scaling

I have a plot of experimental data and the x-axis is scaled from

, but I want it to be scaled in powers of 10 from

. What could I do to fix this axis scaling issue?

Any help would be greatly appreciated!

Set xlim to the limits you want.

Example —

x = logspace(5, 6, 25);                         % Create Data

y = rand(size(x));                              % Create Data
figure
semilogx(x, y)
grid
xlim([1E2 1E6])

MATLAB: Change scaling of x-axis

Try this:

x = 0:260;                                              % Create Data

y = rand(size(x));                                      % Create Data
figure(1)
plot(x, y)
xt = get(gca, 'XTick');                                 % 'XTick' Values
set(gca, 'XTick', xt, 'XTickLabel', xt/140)             % Relabel 'XTick' With 'XTickLabel' Values

The set call relabels the 'XTick' values with the same values divided by 140.

MATLAB: How to plot a second axis which scales with the inverse of the original axis

I’m having a bit of a problem following your code, but you can label your second axis with whatever you want using set with gca and 'XTick' and 'XTickLabel'.

For example:

set(gca, 'XTick', axes.XLim, 'XTickLabel', Clim)

I’m not certain that’s exactly what you want, so experiment with it since I may have misunderstood your variables.
