how to draw annotations in view coordinates?

[whfolsom4]

Apologies if this has been posted elsewhere - my search did not turn up a relevant answer. I have an issues with JFreeChart annotations - I would like to draw one of several Shapes at a given size, say 10x10 pixels. However, the Annotation API appears to require data space coordinates.

I am able to calculate this using the java2DToValue() method after the plot has been rendered, but this causes two side effects:
1. I cannot initially add the annotations prior to the XYPlot beign realized because this method returns Double.Infinity in that case.
2. If I zoom the plot, the annotation is scaled as well.

I would actually like to draw a specific shape in Java2D graphics context coordinates. Is this possible?

Thanks!

I ended up implementing my own subclass of AbstractXYAnnotation which translates but does not scale the Shape to solve problem #2. This also fixes problem #1 because the call to java2DToValue() is now made within the annotation's draw() method, not before the chart component has been realized.

Can you provide your changes? I'm looking to do something similar and would love to avoid developing the same solution...
