New feature.
Plot styles with errorbars avoid obscuring the central point by placing
a white circle behind it.  You can turn this off by saying "unset pointintervalbox"


gnuplot> help with xyerrorbars    
The `xyerrorbars` style is only relevant to 2D data plots.  `xyerrorbars` is
like `points`, except that horizontal and vertical error bars are also drawn.
At each point (x,y), lines are drawn from (x,y-ydelta) to (x,y+ydelta) and
from (x-xdelta,y) to (x+xdelta,y) or from (x,ylow) to (x,yhigh) and from
(xlow,y) to (xhigh,y), depending upon the number of data columns provided.
The appearance of the tic mark at the ends of the bar is controlled by
`set errorbars`.  The clearance between the point and the error bars is
controlled by `set pointintervalbox`. To have the error bars pass directly
through the point with no interruption, use `unset pointintervalbox`.
Either 4 or 6 input columns are required.

     4 columns:  x  y  xdelta  ydelta
     6 columns:  x  y  xlow  xhigh  ylow  yhigh
