MATLAB: Import figure with subplots

subplot

Hi there,

simple question. I want to import a figure which is made of a number of subplots and does something with it. How to handle that? I mean, how to access each single subplot and modify something in a loop, for instance?

Cheers. C

FigH = hgload(FigFileName);
% EDITED: 'flat' without leading '-'
AxesList = findobj(get(FigH, 'Children'), 'flat', 'Type', 'axes');
% If there are additional AXES objects in the figure, 
% which are no SubPlot's use an additional property
% to exclude/include them in the FINDOBJ command.
for aAxes = reshape(AxesList, 1, [])
  set(aAxes, 'Color', rand(1, 3));
end

MATLAB: Tabbed plots removes the title and labels

The issue is because you are not setting the xlabel,ylabel,title to particular axis or figure. These values are automatically set for the figure that is declared recently.Instead of declaring all the figures before ,you could modify your code as below

figure_handles(1).mainfig = figure;
figure_handles(1).tabgroup = uitabgroup;
% Fig1, tab1
newtab = uitab(figure_handles(1).tabgroup, 'Title', "tab1");
ax1 = axes(newtab); 
plot(ax1,rand(1,100)*10,rand(1,100)*10);
title('FIG 1')
xlabel('X label')
ylabel('Y label')
% Fig1, tab2 with legend
newtab = uitab(figure_handles(1).tabgroup, 'Title', "tab2");
ax3 = axes(newtab);
plot(ax3,rand(1,100)*10,rand(1,100)*10);
hold on
plot(ax3,rand(1,100)*10,rand(1,100)*10);
legend('1', '2')
title('FIG 1')
xlabel('X label')
ylabel('Y label')
hold off
figure_handles(2).mainfig = figure;
figure_handles(2).tabgroup = uitabgroup;
% Fig2, tab1
newtab = uitab(figure_handles(2).tabgroup, 'Title', "tab1");
ax = axes(newtab); 
plot(ax,rand(1,100)*10,rand(1,100)*10);
title('FIG 2')
xlabel('X label')
ylabel('Y label')

MATLAB: How to give labels and title to all subplot one time

One may use FINDOBJ to locate all subplots/axes on a figure and then use a FOR loop to label/title all the subplots. For example:

f=figure;
subplot(2,2,1:2)
text(.5,.5,'subplot(2,2,1:2)',...
    'FontSize',14,'HorizontalAlignment','center')
subplot(2,2,3)
text(.5,.5,'subplot(2,2,3)',...
    'FontSize',14,'HorizontalAlignment','center')
subplot(2,2,4)
text(.5,.5,'subplot(2,2,4)',...
    'FontSize',14,'HorizontalAlignment','center')
ax = findobj(f,'Type','Axes');
for i=1:length(ax)
    ylabel(ax(i),{'Nice'})
    title(ax(i),{'Very Nice'})
end

Hope this helps.

Abhi...
