Xerrorlines
The xerrorlines style is only relevant to 2D data plots.
xerrorlines is like linespoints, except that a horizontal error
line is also drawn. At each point (x,y), a line is drawn from (xlow,y)
to (xhigh,y) or from (x-xdelta,y) to (x+xdelta,y), depending on how
many data columns are provided. A tic mark is placed at the ends of
the error bar (unless set bars is used -- see set bars (p.
) for details).
The basic style requires either 3 or 4 columns:
3 columns: x y xdelta
4 columns: x y xlow xhigh
