Markers in XYPlot

[tmtjond]

Currently, in XYPlot, the set of different markers (foregroundRangeMarkers, backgroundRangeMarkers, etc) map an index to a list of markers.
Moreover, it supports to clear the whole list of markers specified to a given index.

However, there may be a high possibility that it requires further sub-dividing the marker lists (diff. series or categories) per index.
Hence, it could group the markers and delete particular 'series' within a nth-index dataset/renderer.

Is it possible that it be will improved in JFreeChart? If not, overriding that 'marker feature' in the subclass seems to be 'duplicated'.

Thanks for your advice.

Any advice?

The reason for assigning an index to a marker is to provide the possibility of the marker being drawn against a secondary axis (if the plot has more than one axis). I can't think of a good reason to allocate a marker to a particular series or item in a dataset. Perhaps you can describe a situation where that would be used?
