I perform large batches of simulations, in which I generate a lot of figures and save them as fig. To avoid, that these figures pop up and make any further work on the machine impossible, I generate these plots in invisible figures. Then i save them as .fig files. This action conserves the property invisible, so that a loading of such a figure only leads to a visible figure, after doing a set(gcf,'visible','on')

I tried to set the state of the visibility in the file on the disk by using the following function:

function makevisible(file)
 f=load(file,'-mat');
 n=fieldnames(f);
 f.(n{1}).properties.Visible='on';   % this line does not have much effect in 16b, used to be the key line in earlier versions.
 f.(n{2}).GraphicsObjects.Format3Data.Visible='on';
 save(file,'-struct','f')
 end

sadly the command: f=load(file,'-mat'); does not only load the data into the workspace struct f, but also generates a figure. This figure then becomes visible, when changing the state. I tried to delete this figure with

close gcf

even before I set the visibility. But this does not only delete the figure, but also alters the data in f. after the close gcf command f is the struct of a "having been deleted figure".

How can I achieve to have saved figure files with visible on, without having every one of these figures to pop up on the screen. ???

My Solution

Its not exactly what I originally wanted, as it still saves the figures invisible. But it solves the described problem by defining a create function, which sets the visibility to on during creation.

 function makevisible(file)
 top  =load(file,'-mat' ,'hgM_070000' );
 top.hgM_070000.GraphicsObjects.Format3Data.CreateFcn  = 'set(gcf,''visible'',''on'')'
 save(file,'-struct','top','-append')
  end

This is a good Idea. Thean I also dont have to care about this hgM_070000 variable name. It is just a

ha.CreateFcn = 'set(gcf,''visible'',''on'')';

Creating callbacks as strings remains dangerous: As soon as a customer has redefined "gcf" in the command window, opening you fig files will produce strange and confusing results.

In older Matlab versions LOAD of a fig file did not open the figure. That this is the case now is rather confusing and impractical.

I repost here the solution, I posted myself in the comments before, in order to be able to "accept" an Anwer:

Its not exactly what I originally wanted, as it still saves the figures invisible. But it solves the described problem by defining a create function, which sets the visibility to on during creation. (Strangely, this procedure was not possible in R2012b where I tried this first. I guess it works since the large figure changes in R2014b(?) )

   function makevisible(file)
   top  =load(file,'-mat' ,'hgM_070000' );
   top.hgM_070000.GraphicsObjects.Format3Data.CreateFcn  = 'set(gcf,''visible'',''on'')'
   save(file,'-struct','top','-append')
    end

This works, but I felt unconfortable about the strange hgM_070000 variable, which has to be used.

Adam then brought up the Idea to make this step directly in the saving application and not as a rework step after saving the file.

This is of course a good Idea. It makes the execution faster, and the fiddling around with this mysterious hgM_070000 Variable falls away.

ha.CreateFcn = 'set(gcf,''visible'',''on'')';

Jan still sees some difficulties in this Method, as gcf might be redefined in the matlab Workspace or path, where the figure is beeing opened.

True, but the unexperienced user will just doubleclick the fig file, and his (perhaps never before used) Matlab installation starts. Little chance of having redefined gcf. And the experienced user should know, that he should not do things like this, or he would know how to deal with the error message.

You can be a little more robust by using gcbo rather than gcf as this is explicitly the handle to the object whose callback is currently executing rather than just the current figure. This function handle approach for the CreateFcn appears to work after a quick test:

@(src,evt)set(gcbo,'visible','on')

Awesome solution Adam, thank you, this works like a charm on R2018b and R2019a.

Are you really sure, that f=load(file,'-mat') opens the figure? This would be very strange.

Is it required to set "f.(n{2}).GraphicsObjects.Format3Data.Visible='on'"? Which Matlab version are you using?

A simply solution would to insert the code to enable the visibility during the loading of the figure.

By "open" I meant that it does the same thing as e.g. uiopen. The complete figure is becoming operative. But additionally to uiopen, I also get the variable f generated. But it would just be enough to get the dead data set of the figure. You can test these simple lines:

 test = figure('visible','off')
 plot([1 10 100],[1 2 3])
 saveas(gcf,  'test.fig')
 close all
 vorher = load('test.fig','-mat');
 set(gcf,'visible','on')

At least it is very unconvinient to not beeing able to set the visibility.

See my comment above to understand why writing a special opening routine is not useful. Of cource I have done this for myself a long time ago.

I use 16b.

When loading the figure file as a struct opens the figure already, this figure must contain any code, which triggers the displaying. What a pitty. This seems to be a perfect example for the bad idea to mix code and data. Blame Mathworks.

Then you could go the hard way: Create the figures invisible at first. Then open all fig files, set the visibility and save the fig fiels again. Although this pollutes your screen, it will do this for a short period of time only.

In older Matlab versions the conversion from a figure to code worked: http://www.mathworks.com/matlabcentral/fileexchange/20152-guidegetter . I'm not sure, if this could be useful for your case.

Would using a command to open the figure that forces it to be visible satisfy your needs? If so use the openfig function with the 'visible' value for the visibility input argument as per the second example on that documentation page.

These figures are intended (not all of them, but some interesting cases) to also be sent to third party matlab users. And then, of course, I always get the reply: "There seems to be something wrong with your figures. They seem to load, at least there is no error message, but nothing does show up. -- Strange " That's exactly the situation I want to avoid.

Yes I could setup a complete ecosystem. But this is then much more complex for the 3rd party user (who perhaps only uses matlab once a month) to install some opener m-files. (where to install, how to set a path, is it dangerous, ...)

Just clicking the fig file in the mail browser is soooooooo much more convienient. !!!
