I'd like to have a separate callback for each bar in a barh plot. Can I get an individual handle to each for this purpose? I tried plotting each bar one at a time, but the Y-axis is all wrong (it appears to keep only the label for the first bar).

You can plot the bars one at a time or in groups that all have the same FaceAlpha level.
That way the bars with differen alpha levels are independent and have their own properties.
Demo:
bounds=categorical({'aa','bb','cc','dd','ee'});bounds=reordercats(bounds,{'aa','bb','cc','dd','ee'});%set(bounds,'Interpreter','latex');
% legend('$\hat{\psi}$','Interpreter','latex')
vals=[1,2,3,4,5];colors = [0 0 1; 1 0 0; 1 0 0; 0 1 0; 0 1 0];alphas = linspace(.08,.9, numel(bounds)); b = gobjects(size(bounds)); cla()hold onfor i =1:numel(bounds) b(i)=bar(bounds(i),vals(i)); set(b(i),'FaceColor',colors(i,:),'FaceAlpha',alphas(i)); endgrid onNever say never!
Y=[ 1 2 3 ; 4 5 6 ; 3 4 5];h = bar3(Y);cm = get(gcf,'colormap'); % Use the current colormap.
cnt = 0;for jj = 1:length(h) xd = get(h(jj),'xdata'); yd = get(h(jj),'ydata'); zd = get(h(jj),'zdata'); delete(h(jj)) idx = [0;find(all(isnan(xd),2))]; if jj == 1 S = zeros(length(h)*(length(idx)-1),1); dv = floor(size(cm,1)/length(S)); end for ii = 1:length(idx)-1 cnt = cnt + 1; S(cnt) = surface(xd(idx(ii)+1:idx(ii+1)-1,:),... yd(idx(ii)+1:idx(ii+1)-1,:),... zd(idx(ii)+1:idx(ii+1)-1,:),... 'facecolor',cm((cnt-1)*dv+1,:)); endendrotate3dNow S has the handle to each surface so you can change the color of each (or set any other individual property) as you wish. I.e, set(S(1),'facecolor','red'). Also, if you knew ahead of time how many surfaces there would be, you could create a matrix of colors and index into that as S was created....
