{it:spec_options} may be specified within a graph specification, globally,
or in both.  When specified in a graph specification, the {it:spec_options}
affect only the specification in which they are used.  When supplied globally,
the {it:spec_options} affect all graph specifications.  When supplied in
both places, options in the graph specification take precedence.  {p_end}


{title:Description}

{pstd}
{opt irf cgraph} makes a graph or a combined graph of IRF results.  Each block
within a pair of matching parentheses{hline 2}each
({it:spec_k}){hline 2}specifies the information for a specific graph.
{opt irf cgraph} combines these graphs into one image, unless option
{opt individual} is also specified, in which case separate graphs for each
block are created.

{pstd}
To become familiar with this command, we recommend you 
type {stata db irf cgraph}.


{title:Options}

{dlgtab:Main}

{phang}
{opt noci} suppresses graphing the confidence interval for each statistic.
    {opt noci} is the default when the model was fitted by {opt vec}
    because no confidence intervals were estimated.

{phang}
{opt set(filename)} specifies the file to be made active;
   see {helpb irf set}.  If {opt set()} is not specified, the active
   file is used.

{dlgtab:Options}

{phang}
{opt level(#)} specifies the default confidence level, as a
    percentage, for confidence intervals, when they are reported. The
    default is {cmd:level(95)} or as set by {helpb set level}.
    Note that the value set of an overall {opt level()} can be
    overridden by the {opt level()} inside a {opt (spec_k)}.

{phang}
{opt lstep(#)} specifies the first step, or period, to be included
    in the graph.  {cmd:lstep(0)} is the default.

{phang}
{opt ustep(#)}, {it:#} {ul:>} 1, specifies the maximum step, or
    period, to be included in the graph.

{phang}
{marker combine_options}{...}
{it:combine_options} affect the appearance of the combined graph;
   see the options available on {helpb graph combine}.  {it:combine_options}
   cannot be specified with {cmd:individual}.

{dlgtab:Plot 1, Plot 2, Plot 3, Plot 4}

{phang}
{opth plot1opts(cline_options)}, ..., {opth plot4opts(cline_options)}
   affect the rendition of the plotted statistics.  {cmd:plot1opts()} affects
   the rendition of the first statistic; {cmd:plot2opts()}, the second; and so
   on.  {it:cline_options} are as described in {it:{help cline_options}}.

{dlgtab:CI 1, CI 2}

{phang}
{opth ci1opts(area_options)} and {opth ci2opts(area_options)} affect the
   rendition of the confidence intervals for the first ({cmd:ciopts1()}) and
   second ({cmd:ciopts2()}) statistics.  See {helpb irf graph} for a
   complete description of this option and {it:{help area_options}} for the
   suboptions that change the look of the CI.

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

{phang}
{it:twoway_options} are any of the options documented in
    {it:{help twoway_options}} excluding {opt by()}.  These include options
    for titling the graph (see {it:{help title_options}}) and options for
    saving the graph to disk (see {it:{help saving_option}}).

{pstd}
The following option is available with {opt irf cgraph} but is not shown in
the dialog box:

{phang}
{opt individual} specifies that each graph be displayed individually.  By
   default, {opt irf cgraph} combines the subgraphs into a single image.


{title:Examples}
