Hi. I have two MATLAB figures and I want to combine them together, meaning to show them on one plot. These two figures have two y-axes. Unfortunately, the code I am using combines only the figures based on the right Y-axes. Can someone help me with this. I am attaching the fig files.
Dir = 'D:\Original_Plots\';
BinSuffix={''}; % Text_followed by number ID
% Load figures
for j = 1:1:length(BinSuffix)
h1(j) = openfig([Dir prefix1 BinSuffix{j} '.fig'],'reuse');
ax1(j) = gca;
for j = 1:1:length(BinSuffix)
h2(j) = openfig([Dir prefix2 BinSuffix{j} '.fig'],'reuse');
ax2(j) = gca;
% Combine figures
for j = 1:1:length(BinSuffix)
hf = figure(20);
hold on;
fig1 = get(ax1(j),'children');
fig2 = get(ax2(j),'children');
s = gca;
xlabel('x1,x2');hold on;
ylabel('y1'); % on left axis
hold on;
ylabel('y2'); % on right axis

Do you only have two files, or do you want to extend it to several files? Also, do you want to keep the current left and right locations of plots the same location in the new figure?

HI, thanks for your reply. I have only two files. I want to keep the same locations of the axes positions. Also, how can I adjust the 'Ylim' for both the y-axes on the left and the right?

Try this code
fig1 = openfig('plot_1.fig');
fig2 = openfig('plot_2.fig');
ax1 = findobj(fig1, 'type', 'axes');
yyaxis(ax1, 'left');
line1L = ax1.Children;
yyaxis(ax1, 'right');
line1R = ax1.Children;
ax2 = findobj(fig2, 'type', 'axes');
yyaxis(ax2, 'left');
line2L = ax2.Children;
yyaxis(ax2, 'right');
line2R = ax2.Children;
fig = figure;
ax = axes();
LineL = copyobj([line1L line2L], ax);
yyaxis(ax, 'right');
LineR = copyobj([line1R line2R], ax);
To change the ylimits you can do something like this
yyaxis(ax, 'left');
ax.YLim = [0 2]; % change Ylimits of left axes
yyaxis(ax, 'right');
ax.YLim = [0 2]; % change Ylimits of right axes

Hi, I have such a similar problem, but using this code results in such too small range of visualized data of the file "VR Acc x".
Can anybody please help me that the range can be set to a nice display of this small data range of the y-axis?
