automatic axis ranges

[Allin C. <cot...@wf...>]

When plotting data with points, if I allow the x- and y-ranges to be 
set automatically they can end up only just encompassing the data, 
such that some points are right on the axes and become almost 
invisible. Here's a trivial example:

plot '-' w p notitle
1.2 3.1
2.2 2.5
3.3 5.0
4.4 3.3
5.5 2.8
e

It takes some visual effort to detect 3 of the 5 points.

I know I can set the xrange and/or yrange manually, but I'm wondering 
if I'm missing some more automated means of saying, in effect, "leave 
a little space around the points".
