{title:Description}

{pstd}
The {it:line_options} determine the look of a line in most contexts.


{title:Options}

{phang}
{cmd:lpattern(}{it:linepatternstyle}{cmd:)}
    specifies whether the line is solid, dashed, etc.
    See {it:{help linepatternstyle}} for a list of available patterns.
    {cmd:lpattern()} is not allowed with {cmd:graph} {cmd:pie};
    see {helpb graph pie}.

{phang}
{cmd:lwidth(}{it:linewidthstyle}{cmd:)}
    specifies the thickness of the line.
    See {it:{help linewidthstyle}} for a list of available thicknesses.

{phang}
{cmd:lcolor(}{it:colorstyle}{cmd:)}
    specifies the color of the line.  See {it:{help colorstyle}} for a
    list of available colors.

{phang}
{cmd:lstyle(}{it:linestyle}{cmd:)}
    specifies the overall style of the line:  its pattern, thickness, and
    color.

{pmore}
    You need not specify {cmd:lstyle()} just because there is something
    you want to change about the look of the line.  The other
    {it:line_options} will allow you to make changes.  You specify
    {cmd:lstyle()} when another style exists that is exactly what you
    desire or when another style would allow you to specify fewer changes.

{pmore}
    See {it:{help linestyle}} for a list of available line styles.

{phang}
{cmd:psytle(}{it:psytle}{cmd:)}
    specifies the overall style of the plot, including not only the linestyle,
    but all other settings for the look of the plot.  Only the 
    {it:{help linestyle}} affects the look of lines.  See 
    {it:{help pstyle}} for a list of available plot styles.


{title:Remarks}

{pstd}
Lines occur in many contexts and, in almost all of those contexts, the above
options are used to determine the look of the line.  For instance, the
{cmd:lcolor()} option in

{phang2}
	{cmd:. graph line y x, lcolor(red)}

{pstd}
causes the line through the ({cmd:y},{cmd:x}) points to be drawn in red.

{pstd}
The same option in, 

	{cmd:. graph line y x, title("My line", box lcolor(red))}

{pstd}
causes the outline drawn around the title's box to be drawn in red.  Note that
in the second command, the option {cmd:lcolor(red)} was a suboption to the
{cmd:title()} option.
