Uistack giving error with yyaxis

I am getting an error when I am trying to move the line plotted on yyaxis (right) to the bottom, so that line plotted on y axis is on top. Below is the code to replicate the error. (Tried on 2019b)

figure

subplot(2,1,1)
yyaxis left
h1=plot(1:10,21:30,'r')
yyaxis right
h2=plot(1:10,rand(1,10),'b','linewidth',10)


subplot(2,1,2)
y=rand(1,10);
h3=plot(1:10,randi(10,1,10),'r')
hold on
h4=plot(1:10,randi(10,1,10),'b','linewidth',10)


uistack(h2,'bottom')
uistack(h4,'bottom')

uistack(h2,'bottom') - Throws an error

Error using matlab.graphics.axis.Axes/set

Children may only be set to a permutation of itself

Error in uistack (line 157)

set(UParent,'Children',AllChildren);

while uistack(h4,'bottom') works without an error & does the job of moving the line to bottom.

Kindly let me know if there is any workaround.

This is has been asked a few times and the only workaround mentioned so far is to use plotyy which is an older method of using 2 y-axes but I would recommend sticking to yyaxis unless it's very important to control the uistack.

@Adam Danz Thanks for confirming & providing a workaround with plotyy. I will stick with yyaxis for now & will wait for uistack to work with yyaxis in a future release.

Appreciate your help..!

Good decision. Be prepared to wait for a while if this feature isn't high on the MW priority list. Another workaround would be to use an axis overlay (general advice on axis overlays) but still, yyaxis is more simpler.
