Auto minor steps possible?

[FSzymanski]

 I am coding a graph that allows users to select data to graph at runtime.  I am currently using auto scaling to set up the axis, but I'm running into some concerns.

First: Is there any way to have minor steps set up in auto scaling?  When the max values is in the hundreds, it looks fine with appropriate steps, but when the max values is small (like 5), the 0-5 with step of 1 doesn't look good.

 Second: Is there any way to add a buffer to the auto scale max?  This graph has point labels set up, but the point with the maximum value has the point label clipping at the top.

Attached is a picture from the application that shows both problems.
