Data points as X axis

Hello,

I have a (probably) simple question.

How do I make the scale on my X-axis just be the points I'm graphing.

Example
if the data I'm graphing on my x axis is:
x
3.4
4.5
6.0
6.3
100.3
1140

I want the scale at the bottom of the graph to consist of only those numbers.
My x-axis is in logarithmic scale in case that is relevant.

Thanks!
