Hi, i have a question:
what is the best approach to extend
http://wiki.apache.org/tapestry/Tapestry5HowToCreateGenericGraphComponent
GenericGraphComponent to output an image map along with the chart
itself.
for now i have only one idea.
1) create and process chart in beginRender to obtain CharRenderingInfo
(needed to produce image map)
2) generate and output image map in beginRender
3) create and process chart again in onChart event to return the
StreamResponce
the obvious issue is the need to generate the chart twice or export it to
image twice. i don't think persisting the chart/input stream is the best
idea, unless there are no other approaches.
