I very much like these enhancements.

And this is just the beginning :-)

Is there a way to set the colors differently for above/below the shifted y axis?  Above is green (no issues); below is red (issues).  Or, depending on what is being discussed, the exact opposite?


Try this:

b := RTGrapher new.
ds := RTStackedDataSet new. 
ds barShape
width: 15;
if: [:v | v < 0 ] fillColor: Color red;
if: [:v | v > 0 ] fillColor: Color green.
ds points: #(5 -6 10 20 -9).
b add: ds.
b axisX noLabel; noTick. b axisY noDecimal.
b build.
