Xyerrorlines
</H1>
The <B>xyerrorlines</B> style is only relevant to 2D data plots.
<B>xyerrorlines</B> is like <B>linespoints</B>, 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. A tic
mark is placed at the ends of the error bar (unless <B>set bars</B> is
used -- see <B>set bars (p. <A HREF="node181.html#set_bars"><IMG ALIGN="BOTTOM" BORDER="1" ALT="[*]" SRC="crossref.png"></A>)<A NAME="2043"></A></B> for details). Either 4 or 6 input columns are required.

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

<P>
If data are provided in an unsupported mixed form, the <B>using</B> filter on the
<B>plot</B> command should be used to set up the appropriate form. For example,
if the data are of the form (x,y,xdelta,ylow,yhigh), then you can use

plot 'data' using 1:2:($1-$3):($1+$3):4:5 with xyerrorlines
