I have multiple figures of data with two y-axes. The left axis shows the histocounts of the values; the right axis gives the cummulative probability of distribution.
I cannot find a way to point to a figure handle and select the left-side ylim data and then reset the ylim values.
Goal: I wish to automatically determine the maximum ylim among the figures to then reset all the plots to the max ylim for easy comparison. The only working "solution" is using yyaxis to select "left" or 'right" and then accessing the ylim values. This however requires that the I manually use gcf after the analysis run and have the figure of interest at the top of the stack.
To summarize: I wish to get the max left-side ylims among a group of figures and then reset all the upper left-side ylims to the group maximum. To further help illustrate this issue, I have included sample data generating fake data for four data sets.
Thank you in advance any help.
datasets = 4;
for n = 1:datasets
data = randn(1,1000*n,4);
f(n) = figure; % fig handles
% plot histogram of random data
histogram(data(:,:,n));
ylabel('counts');
% overlay a cummulative distrib plot
hold on;
yyaxis right;
cdfplot(data(:,:,n));
ylabel('cummulative plot');
title(sprintf('phony balony data set #%s',num2str(n)));
end
%% trying to access the left side axis values
% (e.g. if trying to access fig f(3), hidden under f(4), assuming fig order untouched).
get(f(3).CurrentAxes);

Rather than using gca here, I'd store the histogram handle by calling it with an output then ask for the axes ancestor of that histogram. That way you don't have to assume that the curent axes is what you think it is (that no one has clicked on a different axes, for example.)
h = histogram(randn(1, 1e5));
ax = ancestor(h, 'axes')
ax =
