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} {title:Conformability} {pstd} {cmd:mm_plot(}{it:X}{cmd:,} {it:plottype}{cmd:,} {it:options}{cmd:)}: {p_end} {it:X}: {it:n x k} {it:plottype}: {it:1 x 1} {it:options}: {it:1 x 1} {it:result}: {it:void} {pstd} {cmd:_mm_plot(}{it:X}{cmd:,} {it:plottype}{cmd:,} {it:options}{cmd:)}: {p_end} {it:X}: {it:n x k} {it:plottype}: {it:1 x 1} {it:options}: {it:1 x 1} {it:result}: {it:1 x 1} {title:Diagnostics} {pstd}None. {title:Source code} {pstd} {help moremata_source##mm_plot:mm_plot.mata} {title:Author} {pstd} Ben Jann, University of Bern, jann@soz.unibe.ch {title:Also see} {psee} Online: help for {bf:{help graph_twoway:graph twoway}}, {bf:{help moremata}} {p_end}
