twoway connected draws connected-line plots. In a connected-line plot,
the markers are displayed and the points are connected.
connected is a plottype as defined in [G-2] graph twoway. Thus the
syntax for connected is
. graph twoway connected ...
. twoway connected ...
Being a plottype, connected may be combined with other plottypes in the
twoway family, as in,
. twoway (connected ...) (scatter ...) (lfit ...) ...
scatter_options are any of the options allowed by the graph twoway
scatter command; see [G-2] graph twoway scatter.
connected is, in fact, scatter, the difference being that by default the
points are connected:
Default connect() option: connect(l ...)
Thus you get the same results by typing
. twoway connected yvar xvar
. scatter yvar xvar, connect(l)
You can just as easily turn connected into scatter: Typing
. scatter yvar xvar
is the same as typing
. twoway connected yvar xvar, connect(none)
