+2010-08-21 Change Axis.set_view_interval() so that when updating an
+ existing interval, it respects the orientation of that
+ interval, and can enlarge but not reduce the interval.
+ This fixes a bug in which Axis.set_ticks would
+ change the view limits of an inverted axis. Whether
+ set_ticks should be affecting the viewLim at all remains
+ an open question. - EF

2010-08-16 Handle NaN's correctly in path analysis routines. Fixes a
bug where the best location for a legend was not calculated
correctly when the line contains NaNs. - MGD
