I have a question which is an extension of a previous question: https://www.mathworks.com/matlabcentral/answers/525423-combine-two-matlab-figures-with-two-y-axes

I want to plot these four figures having secondary y-axis (attached) as sub-plots, in 2 rows and 2 columns. My code plots only one set of data from each figure. What are the corrections to the code below to make it work for secondary y-axes?

I have problem with the y-ticks, ylabels and ylimits. I have mentioned the details in the code below. I want the Ylim[0,2] for left y-axis and Ylim[0,5] for right y-axis.

Any help will be appreciated.

Dir = 'D:\Expt_Results\'
prefix='plot_';
BinSuffix=[1:4];
% Load figures into handles
for j = 1:1:length(BinSuffix)
    h(j) = openfig([Dir prefix num2str(BinSuffix(j)) '.fig'],'reuse');
    ax(j) = gca;
end
% Subplot loop 
Fig_dim=[13 12];
hf = figure('Units','inches','Position',[0 0 Fig_dim]);
row_count = 0;
sp_count = 0;
no_rows=2;
no_cols=2;
for i = 1:length(BinSuffix)
    
    fig = get(ax(i),'children');
    s(i) = subplot(no_rows,no_cols,i);
    copyobj(fig,s(i));
    
    sp_count = sp_count + 1;
    sp(sp_count) = s(i);
end

在 MATLAB Online 中打开

Try this code

BinSuffix = 1:4;
% Load figures into handles
h = gobjects(1, numel(BinSuffix));
ax = gobjects(1, numel(BinSuffix));
for j = 1:1:length(BinSuffix)
    h(j) = openfig(['plot_' num2str(j)]);
    ax(j) = gca;
end
%%
fig = figure;
ax_new = gobjects(1, numel(BinSuffix));
for i=1:numel(ax)
    ax_new(i) = subplot(2,2,i);
    
    yyaxis(ax_new(i), 'left');
    yyaxis(ax(i), 'left');
    LineLeft = ax(i).Children;
    copyobj(LineLeft, ax_new(i));
    ax_new(i).YLim = [0 2];
    
    yyaxis(ax_new(i), 'right');
    yyaxis(ax(i), 'right');
    LineRight = ax(i).Children;
    copyobj(LineRight, ax_new(i));
    ax_new(i).YLim = [0 5];
end
