Hi, I attached a PNG file to further clarify the problem. As Steve said, the only purpose of doing this transformation is to generate uniformity for your figures. It's just easier to understand if only the genomic data is plotted in the manner independently form the reading direction of the genes (and data).

Ok, so the inflection point would be the edge of the currently displayed region? And I assume that you don't really want to rotate everything, do you? Still not convinced that this fits into the Gviz world which is quite intimately linked to genomic coordinates. One thing I could see here is to control the plotting direction for everything, I.e., plot all features in a 3->5 direction, however that would not help in those cases where there is a mixture of features on both strands. We do need some sort of reference to place track elements, and within one track I do not see how this reference could be e mixture of 5->3 and 3->5 directions. If just being able to control the plotting direction for a given track solves the issue for you I would be willing to implement that.
