{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:rcapsym} plots a range using spikes capped with marker
symbols.


{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.

INCLUDE help gr_blspikef2

{phang}
{it:marker_options}
    specify how the markers look, including
    shape, size, color, and outline;
    see {it:{help marker_options}}.  The same marker is used on both ends of
    the spikes.

{phang}
{it:marker_label_options}
    specify if and how the markers are to be labeled.  Because
    the same marker label would be used to label both ends of the spike,
    these options are of limited use in this case.
    See {it:{help marker_label_options}}.

{title:Remarks}

{pstd}
We have daily data recording the values for the S&P 500 in 2001:

	{cmd:. sysuse sp500, clear}

	{cmd:. list date high low close in 1/5}
	{txt}

{pstd}
We will use the first 37 observations from these data:

	{cmd:. twoway rcapsym high low date in 1/37}
