New issue 1100 by [hidden email]: Unhandled division by zero in  
Charter
https://code.google.com/p/moose-technology/issues/detail?id=1100

In Charter, I get divide by zero exception when y values are zero. Here is  
an example to reproduce the bug:

| b data minDate view color |
        view := RTView new.
        b := RTCharterBuilder new.
        b view: view.
        b extent: 400 @ 200.
        data := {DateAndTime now -> 0 . DateAndTime now + 200 -> 0} asDictionary.
        minDate := data keys min.
        color := Color random.
       
        b interaction popupText: [:each | each ] .
        b shape ellipse
                size: 10;
                color: color.
        b points: data keys.
        b
                x: [ :aDate | aDate asUnixTime - minDate asUnixTime ];
                y: [ :each | data at: each ].
        b connectDotColor: color.
        b axisConfiguration
                labelRotation: -30;
                minValue: 1000;
                numberOfTicks: data keys size -1;
                labelConvertion: [ :v | (DateAndTime fromUnixTime: (v + minDate  
asUnixTime)) asDate].
        b axisX.
        b build.

Same applies for Grapher when Y values are zero.
