Thread Subject: coloring and customizing scatter plots

hello,

suppose i have the following scatter plot:

x=5*randn(1000,1);
y=.5*randn(1000,1);
lh=scatterhist(x,y);
bc=get(gcf,'color');
set(lh(2:3),'visible','on','color',bc,'box','off');
set(lh(2),'xtick',[],'xcolor',bc);
set(lh(2),'yticklabel',abs(get(lh(2),'ytick')));
set(lh(3),'ytick',[],'ycolor',bc);
set(lh(3),'xticklabel',abs(get(lh(3),'xtick')));

how can i set the color of the scatter plot? i tried setting
'MarkerFaceColor' on the return of scatter hist but it does not work..
how can i get the scatter plot's plot handle?

also, i tried resetting the position of the axes. while:

set(lh(2), 'yaxislocation', 'right');

works, doing the same for lh(1) does not. how can i change its axis?

finally, is there a way to get the two marginal histograms to not only
use the same number of bins, but use the same bins in particular? that
way histograms can be compared

thank you.
