{phang}{opt maxlength(#)},
an option used with all but {cmd:estat summarize},
specifies the maximum number of characters for object names; the default is {cmd:maxlength(12)}.

{phang}{opt format(%fmt)},
an option used with {cmd:estat config}, {cmd:estat correlations},
{cmd:estat quantiles}, and {cmd:estat stress}, specifies the display format;
the default differs between the subcommands.

{phang}{opt nototal},
an option used with {cmd:estat correlations}, {cmd:estat quantiles},
and {cmd:estat stress}, suppresses the overall summary statistics.

{phang}{opt notransform},
an option used with {cmd:estat pairwise}, {cmd:estat quantiles}, and
{cmd:estat stress}, suppresses the linear transformation of the
dissimilarities to match the fitted Euclidean distances.

{phang}{opt full},
an option used with {cmd:estat pairwise},
displays a row for all pairs (j1,j2).  The default is to display rows only for
pairs with j1>j2.

{phang}{opt separator},
an option used with {cmd:estat pairwise},
draws separating lines between blocks of rows corresponding to changes in the
first of the pair of objects.

{phang}{opt labels},
an option used with {cmd:estat summarize},
displays variable labels.

{dlgtab:Main}

{phang}{opt dimensions(# #)}
identifies the dimensions to be displayed.  For instance,
{bind:{cmd:dimensions(3 2)}} plots
the third dimension (vertically) versus the second dimension (horizontally).
The dimension number cannot exceed the number of extracted dimensions.  The
default is {cmd:dimensions(2 1)}.

{phang}{opt xnegate}
specifies that the data should be negated relative to the {it:x}-axis.

{phang}{opt ynegate}
specifies that the data should be negated relative to the {it:y}-axis.

{phang}{opt autoaspect}
specifies that the aspect ratio is to be automatically adjusted based on the
range of the data to be plotted.  This option can make some plots more
readable.  By default, {cmd:mdsconfig} uses an aspect ratio of one, producing
a square plot.  Some plots will have little variation in the {it:y}-axis
direction, and use of the {opt autoaspect} option will better fill the
available graph space while preserving the equivalence of distance in the
{it:x-} and {it:y}-axes.

{pmore}
As an alternative to {opt autoaspect}, the {it:twoway_option}
{help aspect_option:aspectratio()} can be used to override the default
aspect ratio. {cmd:mdsconfig} accepts the {cmd:aspectratio()} option as
a suggestion only, and will override it when necessary to produce plots
with balanced axes, i.e., distance on the {it:x}-axis equals distance
on the {it:y}-axis.

{pmore}
{it:{help twoway_options:twoway_options}} such as {cmd:xlabel()},
{cmd:xscale()}, {cmd:ylabel()}, and {cmd:yscale()} should be used with
caution.  These options are accepted, but may have unintended side effects on
the aspect ratio.

{phang}{opt maxlength(#)}
specifies the maximum number of characters for marker labels; the default is {cmd:maxlength(12)}.

{phang}
{it:cline_options}
affect the rendition of the lines connecting the plotted points; see
{it:{help cline_options}}.  Note that if drawing connecting lines, then
the appearance of the plot depends on the sort order of the data.

{phang}
{it:marker_options}
affect the rendition of markers drawn at the plotted points, including
their shape, size, color, and outline; see {it:{help marker_options}}.

{phang}
{it:marker_label_options}
specify if and how the markers are to be labeled; see
{it:{help marker_label_options}}.

{dlgtab:Y-Axis, X-Axis, Title, Caption, Overall}

{phang}{it:twoway_options}
are any of the options documented in {it:{help twoway_options}} excluding
{cmd:by()}.  See {opt autoaspect} above for a warning against using options
such as {cmd:xlabel()}, {cmd:xscale()}, {cmd:ylabel()}, and {cmd:yscale()}.

{phang}{opt separate}
displays separate plots of each value of the id-variable.  Note that this may
be time consuming if the number of distinct id-values is not small.

{phang}{opt notransform}
suppresses the linear transformation of the dissimilarities to match the
fitted Euclidean distances.

{phang}{opt autoaspect}
specifies that the aspect ratio is to be automatically adjusted based on the
range of the data to be plotted.  By default, {cmd:mdsshepard} uses an aspect
ratio of one, producing a square plot.

See the description of the {opt autoaspect} option of {cmd:mdsconfig} for more
details.

{opt byopts(by_option)}
is documented in {it:{help by_option}}.  This option affect the appearance
