You can try something like that:

     b := Bag new.
     b add: 1 withOccurrences: 5.
     b add: 3 withOccurrences: 4.
     b add: 6.
     b.

    v := RTDoubleGraphBuilder new.
    ds:=RTStackedDataSet new.
    ds interaction popup.
    ds points: b valuesAndCounts keys.
    ds y:[:c|cb valuesAndCounts at: c].
    ds barShape color: Color red; width: 15.
    v add: ds.
    v axisX.
    v axisYWithNumberOfTicks: 5.
    v open

I'm working with an old version of Roassal (version 761 of the Roassal package) then I don't know if it's working with a more recent version.

Otherwise there is examples in the Grapher Menu of the Roassal examples.
