Stacked histograms

    Jun 10 2014 | 8:17 pm
    Hi there, I am using the coll object to parse an excel file in order to draw histograms with a multislider. However I am bit stuck as I am trying to create 'stacked' histograms, while it looks like the multislider object only allows me to draw individual histograms. Perhaps it is something very simple, I have been searching on the forum and in the tutorials but I couldn't find anything like that, so I was wondering... anybody has any idea or suggestion regarding how I could achieve anything like the attached image? Many thanks in advance for all your help.
