How to do scaled x axis for uneven axis ranges in line graph.

Hi, here is what i tried and i couldn't find a way to do it in a line 
graph. I got a dataset which varies based on time and the variation is 
not even, eg. refer to the sample dataset

fuel price changes in cents:

01 March - 127
07 March - 125
09 March - 130
10 March - 133
18 March - 131

in this simple example, i have data for uneven intervals, i need to make 
a graph for all the changes, which is scaled. can anyone done this 
before? can anyone help me on how to do this?
