In 1.0.12, calling setFixedRangeAxisSpace() for a CombinedDomainXYPlot no longer sets the axis width as it did before. Instead it recalculates with an axis space containing all 0s. Calling this function using 1.0.9, the axis space that I send in is used in the draw method to calculate the axis width and the space is set appropriately. It looks like the patch added for bug 1377431 is causing this to occur, as it is resetting the fixedAxisWidth to null, overwriting the values I previously sent in. This code is not present in 1.0.9 that works correctly. (Link to bug: http://sourceforge.net/tracker2/index.php?func=detail&aid=1377431&group_id=15494&atid=115494\) Attaching a snippet that demonstrates the behavior which works correctly when run with .9 but not .12.
