When I transpose the X and Y axes in the xYplot command, the error bars disappear (no surprise given the help file).  It there a way to get the plot command to flip the axes? That would be ideal as I could use the grouping functions in xYplot and save a bunch of work.

xYplot only supports vertical error bars
