[Moose-dev] Trouble with Eyesee

Hi! I am a newbie in Smalltalk and specially en Eyesee. I'm having trouble with the scale of the Y axis in a vertical bar diagram. If I define a dictionary as d := {'a'->(1/3) . 'b'->(3/2) . 'c'->(7/4)}. I can create a nice diagram with this chart := ESDiagramRenderer new. chart verticalBarDiagram y: [:eachAssociation | eachAssociation value]; identifier: [:eachAssociation | eachAssociation key]; regularAxis; models: d . chart open whose Y axis is very well populated with labels indicating different steps in the scale. But if I redefine d as d := {'a'->(1/3) . 'b'->(7/5) . 'c'->(17/4)}. (which is closer to the data I am working on) most of the labels in the Y axis are gone. How can I instruct Eyesee to show a more informative scale? Thanks in advance for your help. Cheers Lautaro Pecile.
