I have x-axis value as 10, 100, 250, 500, 1000, 2000

and y-axis values between 0 and 1. I am comparing 10 values, with 10 line plots on single graph.

I want equal gap between the points of x-axis. I used the command: 
set(gca,'XTick',[10, 100, 250, 500, 1000, 2000])

But, it is not displaying equal gaps. What I mean to say is that x-axis should be divided into 6 (above) points with equal spaces, as in my graph, since variation is higher from point 10 to 250, so lines are very congested. Any help in this regard please?
