{title:Description}

{pstd}
{it:connectstyle} specifies if and how points in a scatter are to be
connected, e.g., via straight lines, stairsteps, etc.

{pstd}
{it:connectstyle} is specified inside the {cmd:connect()} option which is
allowed, for instance, with {cmd:scatter}:

	{cmd:. scatter} ...{cmd:, connect(}{it:connectstylelist}{cmd:)} ...

{pstd}
In this case, a {it:connectstylelist} is allowed.
A {it:connectstylelist} is a sequence of {it:connectstyles} separated by
spaces.  Shorthands are allowed to make specifying the list easier;
see {it:{help stylelists}}.


{title:Remarks}

{pstd}
Points are connected in the order of the data, so be sure that data are
in the desired order (which is usually ascending value of {it:x}) before
specifying the {cmd:connect(}{it:connectstyle}{cmd:)} option.
Commands that provide {cmd:connect()} also provide a {cmd:sort}
option, which will sort by the {it:x} variable for you.

{pstd}
{cmd:connect(l)} is the most common choice.

{pstd}
{cmd:connect(J)} is the appropriate way to connect the points of empirical
cumulative distribution functions (CDFs).
