Quick Gviz question:

For a DataTrack, there is an option to add a legend via setting legend=TRUE

I'm using the feature argument in GeneRegionTrack to color different features. Is there a way to add a legend to the track indicating what the colors mean? Simply supplying legend=TRUE does not work.

Currently it is implemented only for DataTrack-Class. Do you have an example code where do you want to use it?

Best, Robert

The use case was manually setting colors of items on a GeneRegionTrack, for example colouring by strand. I figured a somewhat hacky workaround: You can use an OverlayTrack, to put a DataTrack with no data but a legend on top of a GeneRegionTrack. You have to do some fiddling to make sure the features plotted don't overlap the legend though.
