{pstd}
{bf:mm_plot() -- Draw plot using Stata's {helpb graph_twoway:graph twoway} command}


{title:Syntax}

{p 15 21 2}
{it:void}{space 2}{cmd:mm_plot(}{it:X} [{cmd:,}
{it:plottype}{cmd:,} {it:options}]{cmd:)}

{p 8 21 2}
{it:real scalar}{space 2}{cmd:_mm_plot(}{it:X} [{cmd:,}
{it:plottype}{cmd:,} {it:options}]{cmd:)}


{p 4 4 2}
where

{p 12 16 2}
{it:X}:  {it:real matrix} containing data (rows are observations, columns variables)

{p 5 16 2}
{it:plottype}:  {it:string scalar} specifying type of twoway plot
(see help {helpb twoway}; default is {cmd:"scatter"})

{p 6 16 2}
{it:options}:  {it:string scalar} specifying options to be passed on
to the graph command


{title:Description}

{pstd}
{cmd:mm_plot(}{it:X}{cmd:)} draws a twoway plot from the contents of
{it:X} using Stata's {helpb graph_twoway:graph twoway} command. The
columns of {it:X} are the variables to be
plotted. {cmd:mm_plot()} aborts with error if the graph command
cannot be executed successfully.

{pstd}
{cmd:_mm_plot()} performs the same action as {cmd:mm_plot()} but
returns the appropriate Stata return code instead of aborting with
error if the graph command cannot be executed
successfully.


{title:Remarks}

{pstd} Examples:

        {com}. {stata "mata: mm_plot(uniform(100,2))"}

        {com}. {stata `"mata: mm_plot(sort(uniform(10,3),3),"line")"'}

        {com}. {stata `"mata: mm_plot(uniform(100,2), "", "msymbol(Th)")"'}{txt}
