	A {it:formula} is composed of any combination of
		{cmd:l}            solid line
		{cmd:_}            (underscore) a long dash
		{cmd:-}            (hyphen) a medium dash
		{cmd:.}            short dash (almost a dot)
		{cmd:#}            small amount of blank space

For a palette displaying each of the above named line styles, type

	    {cmd:.} {bf:{stata palette linepalette}} {...}
[{cmd:,} {cmdab:sch:eme:(}{it:schemename}{cmd:)}]

{pin}
Other {it:linepatternstyles} may be available; type

{phang3}
{cmd:. {bf:{stata graph query linepatternstyle}}}

{pin}
to obtain the complete list of {it:linepatternstyles} installed on your
computer.


{title:Description}

{pstd}
A line's look is determined by its pattern, thickness, and color; see 
{help lines}.  {it:linepatternstyle} specifies the pattern.

{pstd}
{it:linepatternstyle} is specified via options named

{phang2}
	<{it:object}><{cmd:l} or {cmd:li} or {cmd:line}>{cmd:pattern()}

{pstd}
or

	<{cmd:l} or {cmd:li} or {cmd:line}>{cmd:pattern()}

{pstd}
For instance, in the case of connecting lines (the lines used to connect
points in a plot) used by {cmd:graph} {cmd:twoway} {cmd:function}, the option
is named {cmd:lpattern()}:

{phang2}
	{cmd:. twoway function} ...{cmd:, lpattern(}{it:linepatternstyle}{cmd:)} ...

{pstd}
In some cases, you will see that a {it:linepatternstylelist} is allowed:

{phang2}
	{cmd:. twoway line} ...{cmd:, lpattern(}{it:linepatternstylelist}{cmd:)} ...

{pstd}
A {it:linepatternstylelist} is a sequence of {it:linepatterns} separated by
spaces.  Shorthands are allowed to make specifying the list easier;
see {it:{help stylelists}}.


{title:Remarks}

{pstd}
While you may choose a prerecorded pattern (e.g., {cmd:solid} or {cmd:dash}),
understand that you can build any pattern you wish by specifying a
line-pattern formula.  For example,

	formula        Description
	{hline 68}
	{cmd:"l"}            solid line, same as {cmd:solid}
	{cmd:"_"}            a long dash
	{cmd:"_-"}           a long dash followed by a short dash
	{cmd:"_--"}          a long dash followed by two short dashes
	{cmd:"_--_#"}        a long dash, two short dashes, a long dash, and a bit
				    of space
	{it:etc.}
	{hline 68}

{pstd}
When you specify a formula, you must enclose it in double quotes.
