Bend error bars?

 Root experts
  I've got 4 TGraphAsymmErrors on the same plot, points all at the same set of x values.  As a result there is considerable overlap of the vertical error bars. In the old hand-drawn days  I would have bent some of the error bars away from the vertical for clarity. Any way to do that  in a ROOT-drawn plot?

  Using Root version 5.12.00 on LINUX.
