Shaded error bar on stair plot

I'm trying to replicate a shaded error bar on a stair plot (attached example)

here is some example data I'm using:

x = (1:1:12)';

y = 100*rand(12,1);

yerr = (3+3)*rand(12,1);

figure
stairs(x,y,'b');
hold on;
errorbar(x,y,yerr,'.');

I've tried several shaded error bar functions from FileExchange with no luck (i.e. https://se.mathworks.com/matlabcentral/fileexchange/26311-raacampbell-shadederrorbar)

Thanks

I've post-edited the plot in a vector editing program to get the desired effect. This has solved my problem for now. Should I close the question?
