Two possibilities:

- Update the `axes` property for the appropriate ranges, affecting all pens for that axis, or
- Dig into [JFreeChart](http://www.jfree.org/jfreechart/api/javadoc/)’s [ValueAxis](http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/axis/ValueAxis.html) types in the configureChart extension function to set limits on a pen-by-pen basis. You would have to interate through the charts datasets (jfreechart datasets – different animal from Ignition datasets) and the pens within them.
