Full chart view?

When I have the verticle axis set to automatic on the Min & Max range it
usually shows a huge distance on the chart because it generally defaults to
0. If the data is 55-100, the chart will start at 0 at the bottom and the
55-100 will be toward the top scrunching the data. Seems like it should size
up the data to best fit everything when on the auto setting. I don't want to
use a fixed setting because if the data changes then I run into a similar
problem. Is there a way to either change the default settings so the charts
will automatically size themselves, or something else I can do to make this
work for me?
