DatasetUtilities.iterateDomainBounds() versus iterateDomainB

[olbrich]

Hi David,

autoScaling for IntervalXYDataset seams to have a bug, doesnt it?

DatasetUtilities.iterateDomainBounds() takes all three values into consideration, but
iterateToFindDomainBounds() doesnt.

1. Why those differences in two methods?
2. ok, if IntervalXYZDataset implies getStartXValue() must be y<= getXValue() <= getEndXValue()
then everything would be ok too.

A little change of some lines in iterateToFindDomainBounds() would help.

best regards
markus

Hi,

It looks like you have spotted a bug. The two methods should give identical results when all series are visible, but as you noted the latter assumes that the x-value is always constrained within the interval...which is wrong. I will create a couple of JUnit tests for this and fix it for the next release. I guess I should check the methods for the rangeBounds also.
