Transparent « Plot « JFreeChart Q&A

1. Transparent plot outputting?

2. Transparency of non-plot area with transparent plot

We have a requirement to have a chart with a transparent plot combined with an opaque non-plot area. Is this possible at this time, and if so how is it brought about (setting the chart background opaque and the plot background transparent doesn't do anything, you're drawing a transparent plot on an opaque background leaving the result opaque).
