Hi all! I want to make a little graph of a vector, with bars:

| b ds labels |
    b := RTGrapher new.
    b extent: 300 @ 200.

    ds := RTStackedDataSet new.
    ds points: { 2 . 2.3 . 1.2 }.

    ds barShape width: 40.
    b add: ds.
    labels := #(x y z - -).
    b axisX numberOfLabels:labels size-1.
    b axisX numberOfTicks:labels size-1.
    b axisX labelConvertion: [ :item | labels at:item +1].
    b build.
    ^ b view

The code above writes the x 2 times. I just want an x, y and z under each one of the bars. Also, I havo to do the 'item+1' thing because it somehow starts at 0, and smalltalk arrays start at 1...

Thanks!
