[{cmd:,}
{it:{help scatter:scatter_options}}]

where {it:varlist} is 

		{it:y_1} [{it:y_2} [...]] {it:x}


{pstd}
{cmd:aweight}s,
{cmd:fweight}s, and
{cmd:pweight}s are allowed; see {help weight}.


{title:Description}

{pstd}
{cmd:connected} draws connected-line plots.  In a connected-line plot,
the markers are displayed and the points are connected.

{pstd}
{cmd:connected} is a {it:plottype} as
defined in {helpb twoway}.  Thus the syntax for {cmd:connected} is

	{cmd:. graph twoway connected} ...

	{cmd:. twoway connected} ...

{pstd}
Being a plottype, {cmd:connected} may be combined with other plottypes in the
{cmd:twoway} family, as in,

	{cmd:. twoway (connected} ...{cmd:) (scatter} ...{cmd:) (lfit} ...{cmd:)} ...


{title:Options}

{phang}
{it:scatter_options}
    are any of the options allowed by the {cmd:graph} {cmd:twoway}
    {cmd:scatter} command; see {helpb scatter}.


{title:Remarks}

{pstd}
{cmd:connected} is, in fact, {cmd:scatter}, the difference being that by
default the points are connected:

	Default {cmd:connect()} option:  {cmd:connect(l ...)}

{pstd}
Thus you get the same results by typing

	{cmd:. twoway connected yvar xvar}

{pstd}
as typing

	{cmd:. scatter yvar xvar, connect(l)}

{pstd}
You can just as easily turn {cmd:connected} into {cmd:scatter}:  Typing

	{cmd:. scatter yvar xvar}

{pstd}
is the same as typing

	{cmd:. twoway connected yvar xvar, connect(none)}
