Yerrorlines
The yerrorlines (or errorlines) style is only relevant to 2D data
plots. yerrorlines is like linespoints, except that a vertical
error line 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. A tic mark is placed at the
ends of the error bar (see set bars (p.
) for details).
Either 3 or 4 input columns are required.
3 columns: x y ydelta
4 columns: x y ylow yhigh
