I'm plotting a BiomartGeneRegionTrack() and some DataTrack() using Gviz for a bunch of genes. This is going fine and the plots look great. I it would be really nice to have all the 5' ends of the genes of interest begin on the left hand side of the track. Is there a way to simply "flip" this track (or any track for that matter) when potting using plotTracks()?
Any suggestions would be greatly appreciated so I don't have to spend hours in illustrator doing this.
