Adjusting the distance between data points on the x-axis
 

This there a way to adjust the distance between data points on the X-axis
based and a data point? For example if I have 2 data points, one accounts
for 40 labor hours and the other accounts for 400. Is it possible to have
the 40 hour data point closer to the last point? When they are the same
distance they look like the represent equal number of hours.
