Ricardo,
I don't believe -graph matrix- can, but you could stitch one together with
-graph combine-
For example:
sysuse auto,clear
graph drop _all
*graph matrix price mpg weight, half name(g1)
twoway lfit mpg price, xscale(off) || scatter mpg price, ///
name(fit1) plotregion(lcolor(black) lwidth(medthick)) ///
ylabel(#4,angle(0) nogrid) ytitle("") nodraw ///
graphregion(margin(4 0 0 0 )) xscale(off) xlabel(#4) legend(off)
twoway lfit weight price || scatter weight price, ///
name(fit2) plotregion(lcolor(black) lwidth(medthick)) ///
ylabel(#4,angle(0) nogrid) ytitle("") nodraw ///
xtitle("") xlabel(#4) graphregion(margin(0 0 0 0)) ///
legend(off)
twoway lfit weight mpg || scatter weight mpg, ///
name(fit3) plotregion(lcolor(black) lwidth(medthick)) ///
ylabel(, nogrid) yscale(off) xtitle("") xlabel(#4) nodraw ///
graphregion(margin(0 0 0 0)) legend(off)
local lab1: variable label price
twoway (scatter mpg price, mcolor(none) ), ///
graphregion(margin(2 0 0 0) fcolor(ltbluishgray) ///
lcolor(ltbluishgray)) plotregion(margin(zero) ///
style(none) fcolor(ltbluishgray8) lcolor(black) ///
lwidth(medium) ) text(27 8000 "`lab1'" ,size(vlarge)) ///
xscale(off) ylabel(,nogrid) yscale(off fill) name(price) nodraw
local lab2: variable label mpg
twoway (scatter mpg weight, mcolor(none) ), ///
graphregion(fcolor(ltbluishgray) lcolor(ltbluishgray) ) ///
plotregion(margin(zero) style(none) lcolor(black) lwidth(medium)) ///
text(26 3300 "`lab2'", size(vlarge)) xscale(off) yscale(off) ///
ylabel(,nogrid) graphregion(margin(0 0 0 0)) name(mpg) nodraw
local lab3: variable label weight
twoway (scatter weight mpg, mcolor(none) ), ///
graphregion(fcolor(ltbluishgray8) lcolor(ltbluishgray8) ) ///
plotregion(margin(zero) fcolor(ltbluishgray8) style(none) ///
lcolor(black) lwidth(medium)) text(3500 27 "`lab3'", ///
size(vlarge)) xscale(off) yscale(off) ylabel(,nogrid) ///
graphregion(margin(0 0 6 0)) name(weight) nodraw
twoway (scatter mpg price, msymbol(point) mcolor(none) ), ///
graphregion(fcolor(ltbluishgray) lcolor(ltbluishgray) ) ///
plotregion(style(none)) xscale(off) yscale(off) ///
name(blank) nodraw
graph combine price blank blank fit1 mpg blank fit2 fit3 weight
Hope this helps,
Scott
