How can I normalize one input for Patch across a subplot?

Hi there, I'm trying to use Patch to show areas of a graph where a certain event is occuring. What I want to do is have these bars show up on every figure in my subplot (which share the same x-axis), but scale the y-axis coordinates for each graph.

I was trying to use copyobj, but the maximum y-axis values are different for each part of the subplot. Here's the code for generating my patches currently - can I use 'Units','Normalized' or something similar for just the y values? Or do I have to manually put these patches into each figure

freeze_logger = [833	1394	10243	10807	19960	20528	29573	30135	38800	39362	48023	48584	57726	58292];
SEC2HRS = 2.7778e-04;

x_freeze = repelem(freeze_logger,2)*60*SEC2HRS;
y_freeze = repmat([-1e5 1e5 1e5 -1e5], 1,length(freeze_logger)/2);
freeze_patch = patch(x_freeze,y_freeze,'red','FaceAlpha',.3);

Use coordinates -inf and +inf . Then you can copyobj . Then in the copied object you can use

max( min(YCoordinates, YUpperBound), YLowerBound )

to compute the new coordinates without needing any logical indexing or anything like that.

So my y_freeze would become:

y_freeze = repmat([-inf +inf +inf -inf], 1,length(freeze_logger)/2);

and then when copying it into a following subplot figure I would do something like this?

freeze_patch1 = copyobj(freeze_patch,ax1);
freeze_patch1.YData = max( min(YCoordinates, YUpperBound), YLowerBound );

I can see what your code is meant to do, just not sure how to incorporate the max(min) part into the copyobj

[Walter Roberson]

freeze_patch1 = copyobj(freeze_patch,ax1);
freeze_patch1.YData = max( min(freeze_patch1.YData, YUpperBound), YLowerBound );

Works perfectly, thank you so much for the help!
