All explicit options are {it:rightmost}, except {cmd:vertical}
and {cmd:horizontal}, which are {it:unique}; see {help repeated options}.


{title:Description}

{pstd}
A range plot has two {it:y} variables, such as high and low daily stock prices
or upper and lower 95% confidence limits.

{pstd}
{cmd:twoway} {cmd:rline} plots the upper and lower ranges
using lines.


{title:Options}

{phang}
{cmd:vertical}
and
{cmd:horizontal}
    specify whether the high and low {it:y} values are to be presented
    vertically (the default) or horizontally.

{pmore}
    In the default {cmd:vertical} case, {it:y1var} and {it:y2var} record the
    minimum and maximum (or maximum and minimum) {it:y} values to be
    graphed against each {it:xvar} value.

{pmore}
    If {cmd:horizontal} is specified, the values recorded in {it:y1var} and
    {it:y2var} are plotted in the {it:x} direction and {it:xvar} is treated
    as the {it:y} value.

{phang}
{it:connect_options}
    change the rendition of the lines connecting the points, including
    sorting, handling missing observations, and the look of the line {hline 2}
    line thickness, pattern, and color.  For details, see help 
    {it:{help connect_options}}.

{title:Remarks}

{pstd}
Visually, there is no difference between

{phang2}
	{cmd:. twoway rline} {it:y1var} {it:y2var} {it:xvar}

{pstd}
and

{phang2}
	{cmd:. twoway line} {it:y1var} {it:xvar} {cmd:||}
		{cmd:line} {it:y2var} {it:xvar}{cmd:, pstyle(p1)}

{pstd}
Note that the two lines are presented in the same overall style, meaning
color, thickness, and pattern.
