Autorange Y-Axis don't work as expected [Solved]

[V.V.V.]

Thank you very much for you explanation.

It's true, Stackoverflow is plenty of questions over JFreechart autorange.
Some try to fix with setIncludeBaseInRange(false).
Others with setAutoRangeIncludesZero(false) or, in the same link, finally make the "roundabout" the setting the limits before call the graphic function.
