Can my x-axis have varying scales for certain ranges of values?

Is it possible to scale my x-axis so the intervals are spread further apart from each other for more time-sensitive data and closer together for the data that spans across a larger time period?
For example, I would like the distance between the x-ticks to be relatively small from 60- to 180-seconds. Conversely, I would like the gaps to be significantly wider from 180-seconds to 200-seconds so the plot is less crowded.

No, it is not.
  • you could create several piecewise linear (or log) axes beside each other, and split the drawing up between them.
  • you could transform your original x data in a non-linear way, and tell xticklabels to lie about what values are there, and ignore the problems you are creating for zoom or data cursors
  • you could transform your original x data in a non-linear way, and tell xticklabels to lie about what values are there, and go through a bunch of trouble to get zoom and data cursors to act sensibly
  • you could create a subplot or inset graph that focused on the area of greatest interest

Yes. You can change the tick locations:
t = 1:200;
x = sinc(2*pi*.125*t);
plot(t, x);
set(gca, 'XTick', [0:20:60 70:10:100 125:25:200])

Yes, but the scale is still uniform across the x-axis correct? In your example, only the labels are located at locations that are not uniform.

You can change the tick location any way you want. The above is just an example.

Here is a simple example:
x = 1:10;
y = 2*x;
figure
plot(x,y)
xtick_loc = [0:0.5:2 3:2:7 8:0.5:10];
set(gca,'XTick',xtick_loc)

Perhaps I was not all that clear with my question. I am trying to scale the data differently along my x-axis. The x-axis still has a uniform scale in your example despite the ticks occurring at different locations.
