I am making a plot like this:
I want to move the green rectangles behind the two bars. Is there any ways to achieve that other than simply chanign the transparency?
Thanks for everyone who answers my question!

Plot the green bars first, before the bar plot.
Alternatively use uistack to control the stacking order of graphics objects.

Thank you for the anwser! I have the code like this:
p = bar(x, vGRF)
p.FaceColor = 'flat';
p.CData(1,:) = r;
p.CData(2,:) = y;
rec1 = rectangle('Position',[0.55, 0.45, 0.9, 0.1],'FaceColor', 'g')
rec2 = rectangle('Position',[1.55, 0.45, 0.9, 0.1],'FaceColor', 'g')
uistack([p])
It seems that uistack only moves the red bar on top of the green box. Is there anyway to access both bars and put them above the boxes?

rec1 = rectangle('Position',[0.55, 0.45, 0.9, 0.1],'FaceColor', 'g')
hold on
rec2 = rectangle('Position',[1.55, 0.45, 0.9, 0.1],'FaceColor', 'g')
p = bar(x, vGRF)
p.FaceColor = 'flat';
p.CData(1,:) = r;
p.CData(2,:) = y;

I tried the method above. The problem was that this step was built in a for loop to plot real-time bar plot. Everytime it runs, the bars were overlayed as well. I tried hold off, which did not solve this problem.
I really appreciate your answer!

hold on
h = plot([0,4],[.5 .5],'k-','LineWidth', 5);

bar(1:3)
hold on
h = plot([0,4],[.5 .5],'k-','LineWidth', 5);
uistack(h,'bottom')
