[guppi-list] Legend on guppitank objects?

[grib gnumatic com (Bill Gribble)]

For some reason I'm not seeing legends on my guppitank objects under
some circumstances.  In a simple demo I have, where I specify all the
colors and labels, I get a legend, but it seems that if I don't
explicitly specify colors no legend shows up.  Is that the way it's
supposed to work? 

Also, in recent Guppi CVS versions, it's possible for barchart objects
to get stuck in a 100%-of-CPU, never-coming-back loop somewhere under
guppi_object_build_widget.  Has this been observed by anybody else?  I
can send a stack trace if it would help.

Thanks,
