When I use matlab's chromosomeplot with addtoplot flag turned on, I cannot get legends on my figure.
  1. If I execute chromosomeplot first, then calls to legend thereafter does not produce a legnd.
  2. If I execute legend first, then a subsequent call to chromosomeplot produces the error "Can not add chromosome to this figure for it contain too many axes"

Can explain in more detail what exactly you're trying to do? It's not clear to me exactly what you are trying to add a legend for and what you expect to appear in a legend. At least by default, the chromosomeplot doesn't have any information that would be added to a legend. But if you're trying to combine a chromosomeplot with some other plot that includes a legend, he's one way to do it:
plot(rand(3))
legend('a', 'b', 'c')
hs_cytobands = cytobandread('hs_cytoBand.txt')
chromosomeplot(hs_cytobands, 1, 'AddToPlot', gca)
