hi together

i have following graph by command

a b c d e
96 16 43 34 16

graph hbar (sum) a b c d e , stack percent ///
blabel(bar , pos(center) format(%4.0f) size(small) color(eltgreen) ) ///
ytitle("Percent", size(small)) ///
title("Distribution" ///
, size(small)) ///
bar(1, color(ltbluishgray)) bar(2, color(bluishgray)) bar(3, color(ltblue)) ///
bar(4, color(ebblue)) bar(5, color(sea)) ///
legend( label( 1 "A") label( 2 "B") label(3 "C") ///
label(4 "D") label(5 "E") ///
size(small) symxsize(4) row(1)) ylabel(, labsize(small))
now i would like to change the position of the ytitle to "east" and no surrounding black box of the graph.
so far, i did it in the graph editor. but is there any command for the changes?

can somebody help me? thanks a lot!
