{title:Description}

{pstd}
The {it:cat_axis_line_options} determine the look of the categorical {it:x}
axis in {cmd:graph} {cmd:bar}, {cmd:graph} {cmd:hbar}, {cmd:graph} {cmd:dot},
and {cmd:graph} {cmd:box}.  These options are rarely specified but when
specified, are specified inside {cmd:axis()} of {cmd:over()}:

{phang2}
	{cmd:. graph} ...{cmd:, over(}{it:varname}{cmd:,} ... {cmd:axis(}{it:cat_axis_line_options}{cmd:)} ...{cmd:)}


{title:Options}

{phang}
{cmd:off} and {cmd:on}
    suppress or force the display of the axis.

{phang}
{cmd:fill} goes with {cmd:off} and is seldom
    specified.  If you turned an axis off but still wanted the space to be
    allocated for the axis, you could specify {cmd:fill}.

{phang}
{cmd:fextend}, {cmd:extend}, {cmd:noextend}, {cmd:line}, and {cmd:noline}
    determine how much of the line representing the axis is to be drawn.  They
    are alternatives.

{pmore}
    {cmd:noline} specifies that the line not be drawn at all.  The axis
    is there, ticks and labels will appear, but the axis line itself will not
    be drawn.

{pmore}
    {cmd:line} is the opposite of {cmd:noline}, for use if the axis line
    somehow got turned off.

{pmore}
    {cmd:noextend} specifies that the axis line not extend beyond the
    range of the axis, defined by the first and last categories.

{pmore}
    {cmd:extend} specifies that the line be longer than that and extend
    all the way across the plot region.

{pmore}
    {cmd:fextend} specifies that the line be longer than that and
    extend across the plot region and across the plot region's margins.  For a
    definition of the plot region's margins, see 
    {it:{help region_options}}.  If the plot region has no margins (which
    would be rare), then {cmd:fextend} means the same as {cmd:extend}.  If the
    plot region does have margins, {cmd:extend} would result in the {it:y} and
    {it:x} axes not meeting.  With {cmd:fextend}, they touch.

{pmore}
    {cmd:fextend} is the default with most schemes.

{phang}
{cmd:titlegap(}{it:relativesize}{cmd:)} specifies the margin to be inserted
     between the axis title and the axis' tick labels.

{phang}
{cmd:outergap(}{it:relativesize}{cmd:)} specifies the margin to be inserted
     outside of the axis title.

{phang}
{cmd:lstyle(}{it:linestyle}{cmd:)},
{cmd:lcolor(}{it:colorstyle}{cmd:)},
{cmd:lwidth(}{it:linewidthstyle}{cmd:)}, and
{cmd:lpattern(}{it:linepatternstyle}{cmd:)}
determine the overall look of the line that is the axis;
see {help lines}.


{title:Remarks}

{pstd}
The {it:cat_axis_line_options} are rarely specified.
