## yerrorbars

The yerrorbars (or errorbars) style is only relevant to 2D data plots. yerrorbars is like points, except that a vertical error bar is also drawn. At each point (x,y), a line is drawn from (x,y-ydelta) to (x,y+ydelta) or from (x,ylow) to (x,yhigh), depending on how many data columns are 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.

         2 columns:  [implicit x] y ydelta
         3 columns:  x  y  ydelta
         4 columns:  x  y  ylow  yhigh

Additional input columns may be used to provide information such as variable point size, point type, or color.
