Display values in horizontal axis in groups

I would like to group the values on the horizontal axis into groups. The values of in hrs and the graph can get pretty wide if there are lots of hours.

I was able to get the axis to change but wanted a specific range that is more customize.

For example, instead of this range:

0 5 10 15 20 25 30 35 40 45 50 55 60

I want it to do this:

0 4 12 24 36 48 72 1wk 2wk 3wk 4wk

Hello,
I have one solution, did you mean something like this?
