Re: Animation problem with newer visad.jar

Hi Doug,

The logic for merging Sets for animation is in the visad/Set.java
and the cvs log doesn't show any relevant changes. Of course, it
could be somewhere else (like Units, ShadowTyoes, etc). However,
the tests I run with every release include tests of the animation
merge logic.

You might try a different approach to your problem. Rather than
adding a dummty Set, try calling the reAutoScale() method of your
DisplayImpl. This should recompute the animation sampling. It
will also reAutoScale any ScalarMaps for which you haven't
explicitly called setRange().

Good luck,
Bill
