How to add constant line y(50) to all plots of stackedplot?

Hi all,

I am using stackedplot with 15 columns in a time table. How can I add a constant line of y(50) to all those 15 graphs in the stacked plot?

Thanks

You can get the axis handles in stackedplot using the undocumented NodeChildren property. Then add the constant line object to each y-axis. Since yline only accepts one axis handle you can do it in a loop or use arrayfun as I have, below.

rng('default')
h = stackedplot(rand(100,5).*10+45);
ax = findobj(h.NodeChildren, 'Type','Axes');
arrayfun(@(axh)yline(axh,50,'m-','LineWidth',1),ax);
