Saving figures into structure?
67 views (last 30 days)
Is it possible to save a figure into a structure? I'm trying to figure out how to save both data and figures into a single entity that I could then load in matlab. I know data can be saved in .mat and figures can be saved as .fig but is there not a way to save both in a single container?

data = rand(10,2);
myStruct.structFig = plot(data);
myStruct.structData = data;
m = figure(2);
% does not actually work
% % set(m,myStruct.structFig.XData,'XData');
you should have a look at the set() command. I haven't found a solution yet. Easiest would be just plot the data again but here you loose all of your preset defines like thickness and such things.

Yes you can by simply save the plotting command (plot, bar, ...) as a string, and then use eval command to excute it. However, keep in mind the the input arguments of the plotting command have to be stored as vectors in other fields in the same structure.
% lets make a 2D plot of x and y values
s.x = [1, 2, 3];
s.y = [4, 5, 6];
s.figure = "plot(s.x, s.y)"
% to plot the figure later

Once a figure is closed, the associated data will be deleted and cannot be directly recovered. The only workaround is to create a class handle class with a transient property, as shown in my answer here: https://www.mathworks.com/matlabcentral/answers/521538-how-can-i-save-a-3d-rendering-as-a-fig
