Hello,

I wrote a program with a GUI. I also made a button for saving the plots as a *.fig file. When I open the saved *.fig file, Matlab opens the import wizard (size= 1267x1894x3 and the class= uint8). When I click on the finish button the data is loaded in the workspace. 

The figure I saved was a polar plot. What can be the problem? The size of the matrix?

Thanks 

Steven

Problem with the way you save the file, possibly. Could you show us the 
relevant lines of code to save the plots to file?

function save_plot_Callback(hObject, eventdata, handles)

savePlotWithinGUI(handles.axes_for_plot);


function savePlotWithinGUI(axesObject, legendObject)
%this function takes in two arguments
%axesObject is the axes object that will be saved (required input)
%legendObject is the legend object that will be saved (optional input)

%stores savepath for the phase plot
% [filename, pathname] = uiputfile({ '*.emf','Enhanced Meta File (*.emf)';...
%         '*.bmp','Bitmap (*.bmp)'; '*.fig','Figure (*.fig)'}, ... 
%         'Save picture as','default');
    
[filename, pathname] =   uiputfile(...
                            { '*.fig','Figure (*.fig)';...
                              '*.eps','Encapsuladed Postscript (*.eps)';...
                              '*.png','Portable Network Graphics (*.png)';...
                              '*.emf','Enhanced Meta File (*.emf)';...
                              '*.pdf','Portable Document Format (*.pdf)'}, ...
                              'Save picture as','untitled');
                             
                          
%                           {'*.m;*.fig;*.mat;*.mdl','MATLAB Files (*.m,*.fig,*.mat,*.mdl)';
%  '*.m', 'M-files (*.m)';...
%  '*.fig','Figures (*.fig)';...
%  '*.mat','MAT-files (*.mat)';...
%  '*.mdl','Models (*.mdl)';...
%  '*.*',  'All Files (*.*)'},...
%  'Save as');



%if user cancels save command, nothing happens
if isequal(filename,0) || isequal(pathname,0)
    return
end
%create a new figure
newFig = figure;
set(newFig,'Visible','off');

%get the units and position of the axes object
axes_units = get(axesObject,'Units');
axes_pos = get(axesObject,'Position');

%copies axesObject onto new figure
axesObject2 = copyobj(axesObject,newFig);

%realign the axes object on the new figure
set(axesObject2,'Units',axes_units);
set(axesObject2,'Position',[15 5 axes_pos(3) axes_pos(4)]);

%if a legendObject was passed to this function . . .
if (exist('legendObject'))

    %get the units and position of the legend object
    legend_units = get(legendObject,'Units');
    legend_pos = get(legendObject,'Position');

    %copies the legend onto the the new figure
    legendObject2 = copyobj(legendObject,newFig);

    %realign the legend object on the new figure
    set(legendObject2,'Units',legend_units);
    set(legendObject2,'Position',[15-axes_pos(1)+legend_pos(1) 5-axes_pos(2)+legend_pos(2) legend_pos(3) legend_pos(4)] );

end

%adjusts the new figure accordingly
set(newFig,'Units',axes_units);
set(newFig,'Position',[15 5 axes_pos(3)+30 axes_pos(4)+10]);
%saves the plot
if(strcmp(filename(end-2:end),'pdf'));
    save2pdf([pathname filename],newFig,600);
else
    harm = 3;
    saveas2(newFig,[pathname filename]);
end

%closes the figure
close(newFig)

I do not recognize saveas2(): is it a locally written function?

Hi,
I also encountered this problem and after spending many hours found the reason. It happens when you click "save as" even though the file has .fig extension the "save as type" is Paintbrush 24-bit file (*.pcx) by default which causes the problem . I don't know how to recover the corrupted files but in future changing the save as type to MATLAB figure (*.fig) helps.
