How to save multiple figures in seperate folders for plot yy axis?

Hi

How can I save multiple figures plotted in double y-axis graphics in seperate folders?

My matlab code for plotyy axis starts as below:

figure;[haxes,hline1,hline2] = plotyy(dat_s,M1_T,dat_s,T);

For one y-axis we use fullfile command, I have asked in my previous question and I have got this answer. But for double yy axis how can I save figures as fig. file and jpg. file in separate folders?

For example;

X.fig and X.jpg in A folder.

and

Y.fig and Y.jpg in B folder.

Thanks a lot..

Same idea, build a fully-qualified file name; in general as with variables it may not be the most effective naming scheme to build sequential folder names to have to traverse, but there's nothing preventing do so. Where, specifically, did you have a problem in doing so and what have you tried so far?

In my previous question I have got this answer:

Fig=plot(rand(1,10));
File=fullfile('c:\MyDirectory','FolderA','MyFigure.fig');
saveas(Fig,File,'fig');

It is ok for one Y-axis graphics. But I tried below command for my own Matlab code for double y axis graphics;

Fig=[haxes,hline1,hline2];
File=fullfile('C:\Users\user\Desktop','A','MyFigure.fig');
saveas(Fig,File,'fig');

When I tried this command; I have an error "Operands to the and && operators must be convertible to logical scalar values."

By the way, my Maltab code starts as below:

[haxes,hline1,hline2] = plotyy(dat_s,M1K2_norm,dat_s,T);

What can do in this case?

In the second, you're trying to concatenate different handle types into a vector which won't work although passing a vector of handles is unsupported syntax to saveas anyway as the fig argument is "Figure to save, specified as A (emphasis added/dpb) figure object...".

The second would work as

Fig=haxes;
File=fullfile('C:\Users\user\Desktop','A','MyFigure.fig');
saveas(Fig,File,'fig');

but why don't you save the figure handle and use it or just write

saveas(gcf,File,'fig');

if at the time of drawing the figure so is current or save the figure handle when it is created and then use it...

hFig=figure;
...
plotting stuff here
...
saveas(hFig,File,'fig')

and you don't need any special code between the two; just create the appropriate filename as desired.

saveas(gcf,File,'fig');

I think this will help me, I have tried. Thanks a lot..

And in my first question above, I have also asked about how to save in png or jpg format again in seperate folders?

I have tried "imwrite" command but it didnt't work.

Could you please help me about this point also?

What point, precisely? SAVEAS can save the figure in one of a dozen or more ways; you simply call it with the desired format string specifically or you can use one of the predefined extension strings when creating the filename and then it will automagically use that to determine the figure type to match. You simply have to choose one way or t'other (or ensure you write code that creates a file and option that match or you can end up with mismatched filenames and types in the associated file). See the doc for details on what are the file types known and assumed extensions that go with them.

Again, how you create a subdirectory structure for the filename is totally independent of the manner in which the data are saved; use fullfile and the other string-handling functions specifically for creating and handling file names for that purpose; only that you must have a fully-qualified filename to ensure you're putting the files where you really intend; otherwise a partially-qualified name or a filename without any directory information will be relative to the location where the function is executed.

Also note that using gcf has some potential for error; if there's any possibility at all that the focus can be shifted by the user from the time the figure is created before it is saved, then you'll get the figure the user has last pointed to, NOT necessarily the one you're intending; hence the recommendation to save the handle to the figure you intend when you create it so you can refer to the desired one unequivocally.

Ok, I will try your suggestion then, ıf I come across any problems, I will ask again.. Thanks a lot for your help..

Sounds like a plan.. :)

The point is, don't mix up what are really independent parts of the problem; naming the file and where you store it are one issue, how you store the data inside it is another.

Granted, one wants an extension to match the content, but ML will take care of that for you automatically unless you want something other than a default value (which is not, generally, a wise thing).
