I would like to keep data from figures using gcf. However, when I close the figure, I lose all the data stored into my variable.
map = randn(10,10);
figure; imagesc(map);
fig = gcf; % I have the data stored into fig
close all;
fig; % Error : handle to deleted Figure
How can I keep data from gcf even if the figure is closed.
You could save your figure as file using saveas before closing it.
When you need it again, you can reload it with open.
Full example:
map = randn(10,10);
figure; imagesc(map);
fig = gcf;
%% Save figure in file 'MyFigureFile.fig'
saveas( fig, 'MyFigureFile', 'fig')
close all;
%% Load figure from file 'MyFigureFile.fig'
open( 'MyFigureFile.fig' );
Other Option:
You could simply hide the figure instead of closing it using fig.Visible = false or fig.Visible = 'off' as suggested in Delete object handle and keep variable in MATLAB.
