Created an attachment (id=316589) --> (http://bugzilla.novell.com/attachment.cgi?id=316589) Example with --rigid: No y scale displayed

(Found in current version of SLES10 SP2, rrdtool-1.2.12-13.2) Specific values (like all between 17.7 and 17.8) cause rrdtool's graph to autoscale the values at a range of 10 to 20, making actual variations practically invisible. There are other intervals where similar problems arise, like [42.0:42.2] where the scale is [40:50]. The --alt-autoscale improves the scaling, but has a problem with not enough numeric labels for the y-axis being shown, just as --rigid does. The author of the tool said the current version is much better regarding those issues.

Reproducible: Sometimes

Steps to Reproduce: 1. Create graphs with automatic scaling where the values vary a little bit around some undetermined value

Actual Results: Some graphs are not good enough to show the variations.

Expected Results: The vertical scale should respect the range of values more that it currently does.
