Adjust Values On Y-Axis of Graph

[uneek78]

How do you adjust the values on the Y-Axis of a graph? I have numbers that represent minutes ranging from 0 minutes anywhere on up to 1200 or so minutes. Since the values are so broad the majority of the values that range between 0-60 minutes have nothing on the y-axis. It has the values
1600
1400
1200
1000
800
600
400
200
0

I would prefer it to be more like

60+
45
30
15
0

Or something I can adjust myself. Is that possible?

if you right-click on the axis, you should see the options for min, max, intervals, among others.

How many times does your data go upto the upper limits ie...1200 minutes?
