{title:Description}

{pstd}
{cmd:query} {cmd:graphics} shows the graphics settings.

{pstd}
{cmd:set} {cmd:graphics} allows you to change whether graphs are
displayed.


{title:Remarks}

{pstd}
If you type

	{cmd:. set graphics off}

{pstd}
when you type a {cmd:graph} command, such as

	{cmd:. scatter yvar xvar, saving(mygraph)}

{pstd}
the graph will be "drawn" and saved in file {cmd:mygraph.gph}, but it will not
be displayed.  If you type

	{cmd:. set graphics on}

{pstd}
graphs will be displayed once again.

{pstd}
Drawing graphs without displaying them is sometimes useful in programming
contexts, although in such contexts, it is better to specify the {cmd:nodraw}
option; see {it:{help nodraw_option}}.  Typing

	{cmd:. scatter yvar xvar, saving(mygraph) nodraw}

{pstd}
has the same effect as typing

	{cmd:. set graphics off}
	{cmd:. scatter yvar xvar, saving(mygraph)}
	{cmd:. set graphics on}

{pstd}
The advantage of the former is that,
not only does it require less typing, but if
the user should press {it:Break}, {cmd:set} {cmd:graphics} will not be left
{cmd:off}.
