I think the circular inferno plot for comparing genome-wide association scan results could be useful.

This is described in this paper:

Tembe WD, Pearson JV, Homer N, Lowey J, Suh E, Craig DW. Statistical comparison framework and visualization scheme for ranking-based algorithms in high-throughput genome-wide studies. J Comput Biol. 2009 Apr;16(4):565-77. PubMed PMID: 19361328.

as well as in this poster (pdf file).

Perhaps such plots could be drawn using the 'circos' software:
