{title:Description}

{pstd}
The shape of the area is determined by context.  The {it:areastyle}
determines whether the area is to be outlined and filled and, if so, how and
in what color.


{title:Remarks}

Remarks are presented under the headings

{marker remarks1}{...}
{title:Overview of areastyles}

{pstd}
{it:areastyle} is used to determine the look of

{phang}
1.  the entire region in which the graph appears{break}
    (see option {cmd:style(}{it:areastyle}{cmd:)} in 
    {it:{help region_options}})

{phang}
2.  bars{break}
    (see option {cmd:bstyle(}{it:areastyle}{cmd:)} in {helpb graph bar} or
    {helpb twoway bar})

{phang}
3.  an area filled under a curve{break}
    (see option {cmd:bstyle()} in {helpb twoway area} or
    {helpb twoway rarea})

{phang}
4.  Most other enclosed areas, such as the boxes in 
    {help graph box:box plots}

{pstd}
For an example using {it:areastyle} {cmd:none}, see
{hi:Suppressing the border around the plot region} in
{it:{help region_options}}.


{* index numbered styles}{...}
{marker remarks2}{...}
{title:Numbered styles}

{phang}
     {cmd:p1bar} - {cmd:p15bar} are the default styles used for bar charts, 
        including {helpb twoway bar:twoway bar} charts and 
        {help graph bar:bar charts}.  {cmd:p1bar} is used for filling and
        outlining the first set of bars, {cmd:p2bar} for the second, and so
        on.

{phang}
     {cmd:p1box} - {cmd:p15box} are the default styles used for 
        {help graph box:box charts}.  {cmd:p1box} is used for filling and
        outlining the first set of boxes, {cmd:p2box} for the second, and so
        on.

{phang}
     {cmd:p1pie} - {cmd:p15pie} are the default styles used for 
        {help graph pie:pie charts}.  {cmd:p1pie} is used for filling the
        first pie slice, {cmd:p2pie} for the second, and so on.

{phang}
     {cmd:p1area} - {cmd:p15area} are the default styles used for area charts,
        including {helpb twoway area:twoway area} charts and 
        {helpb twoway rarea:twoway rarea} charts.  {cmd:p1area} is used for
        filling and outlining the first filled area, {cmd:p2area} for the
        second, and so on.

{phang}
     {cmd:p1} - {cmd:p15} are the default area styles used for other plot types,
        including
	{helpb twoway dropline} charts,
        {helpb twoway spike} charts,
        {helpb twoway rspike} charts,
        {helpb twoway rcap} charts,
        {helpb twoway rcapsym} charts, and
        {helpb twoway rline} charts.    
        {cmd:p1} is used for filling and outlining the first plot,
        {cmd:p2} for the second, and so on.  Note that for all of the plots
	listed above, only lines are drawn, so the shade settings have no
	effect.


{marker remarks3}{...}
{title:Using numbered styles}

{pstd}
        The look defined by a numbered style, such as {cmd:p1bar},
        {cmd:p2area}, etc., is determined by the {help schemes:scheme}
        selected.  By "look" we mean such things as color, width of lines,
        patterns used, etc.

{pstd}
        Numbered styles provide default "looks" that can be
        controlled by a scheme.  They can also be useful when you wish to
        make, say, the third element on a graph look like the first.  You can,
        for example, specify that the third bar on a bar graph be drawn with
        the style of the first bar by specifying the option 
        {cmd:barstyle(3, bstyle(p1bar))}.


{marker remarks4}{...}
{title:When to use areastyles}

{pstd}
You can often achieve an identical result by specifying an {it:areastyle}
or using more specific options, such as {cmd:fcolor()} or {cmd:lwidth()},
that change the components of an areastyle{hline 2}the fill color and outline
attributes.  You can even specify an {it:areastyle} as the base and then
modify the attributes using more specific options.  It is often easiest to
specify options that affect only the fill color or a single outline
characteristic rather than to specify an areastyle.  If, however, you are trying
to make many elements on a graph look the same, specifying the overall
{it:areastyle} may be preferred.
