Re: Coordinates for XYShapeAnnotation?
The shape's coordinates are data coordinates, not screen coordinates. A typical concrete implementation of java.awt.Shape contains nested classes with constructors that accept float or double arguments, e.g. Ellipse2D.Double in the first example cited.

Re: [XYPlot][ChartEditor] How to customize ChartEditor for a double range axis
While the relevant classes aren't public, they do have package-private access in org.jfree.chart.editor . You'll have to clone the repository, but you should be able to modify DefaultPlotEditor::createPlotTabs to (conditionally) include as many additional instances of DefaultAxisEditor as needed.

Re: Impossible to change order of legend items???
Right. Addition order is meant to accommodate varying layouts; see fetchLegendItems() for details. For alphanumeric sorting, you might be able to override the method with your own implementation that adds the items in lexicographic order.

Re: Impossible to change order of legend items???
SortOrder.ASCENDING is the default SortOrder for a LegendTitle. What happens if you specify SortOrder.DESCENDING?

Re: XY chart, interval painting related to Y-axel values
A suitable Marker might work for the color ranges, and a suitable Annotation might work for the images.
