Re: Regarding plotting stacked histograms with custom colors

Hi Ethan

Thank you for the solution. Each Y column will be a score for a particular
amino acid. The Y columns will be in increasing order of the score value.
Each Z will always correspond to a particular color we use to represent the
amino acid that will be in the corresponding y column. We will use a set of
20 colors to represent 20 amino Acids.
