I'm trying to create a ticks distribution like the one in figure

...I really can't figure how to do it. Do I have to define the x-variable in a particular way or is it just an axis and ticks thing ?

Have you tried semilogx? Is this close enough?

I did use the semilogx and specified certain ticks values. Thanks for helping !

Hi Francesco, take a look at this documentation page if you haven't already: Specify Axis Tick Values and Labels

There is also an example of setting nonuniform x-axis tick locations on the documentation page for 'xticks'.

adding to this (5/14/20): It looks like you also wanted to use a logarthmic scale for the x-axis and semilogx was already suggested.

You can also use xlim to specify limits for the x-axis.

I'm not sure why this answer was accepted... the question as I understand it is about stretching and compressing the x axis, not just speciftying xticks or xticklabels. The documentation pointed out does not contain information on stretching/compressing axes.

Thanks LR, I edited my answer to include the links to documentation for setting a log scale and limits on the x-axis, which had already been suggested in the comments.
