-- Bug description --
bar(): vectorize the color option. When several histogrammes are plotted in a once, the color property might be a vector with one component per histogramme.
Presently, the explicit color property must be a scalar, when one aims to change the default colors. Then, all histogrammes are plotted with the same explicit color -- either in grouped or in stacked modes --, which is of no interest. A vector of respective colors is not accepted , while it would be the only interest of such an option.
