评论： Zack Morris 2023-12-8

I created a code to display my plots onto a Powerpoint (PPT) slide. The issue lies with MATLAB would generate all the plots but would only display the last plot on all the PPT slides. So far the only method is to copy the for loop, change the range (ex: 1:1, 2:2, 3:3, etc) and the "plot.png" numerical. I want to eliminate this tedious method and have an easier method for each slide to display each corresponding plot.

In this example length(fileList) = 6. The fileList respresents the 6 plots generated in this example. Prior I had length(fileList) in the for loop but it would only display the last plot on the slides.

X1 = length(fileList);

for j = 1:1 %length(fileList)

imgFIG = openfig(strcat(fileList(j).folder,'\',fileList(j).name));

saveas(imgFIG,'plot.png');

imgPNG = imread('plot.png');

imgPNG2 = imresize(imgPNG, 1.5);

imwrite(imgPNG2,'plot2.png')

imgPNG3 = Picture('plot2.png');

fName = fileList(j).name;

z = fName(27:28);

dataSlides = add(ppt,'Title and Content');

newTitle = strcat('Step', {' '}, z,' Simulations');

replace(dataSlides,'Title', newTitle);

replace(dataSlides,'Content', imgPNG3);

clearvars -except j pL ppt directory fileList dirSize X1

end

for j = 2:1:X1

imgFIG = openfig(strcat(fileList(j).folder,'\',fileList(j).name));

saveas(imgFIG,'plot4.png');

imgPNG = imread('plot4.png');

imgPNG2 = imresize(imgPNG, 1.5);

imwrite(imgPNG2,'plot5.png')

imgPNG3 = Picture('plot5.png');

fName = fileList(j).name;

z = fName(27:28);

dataSlides = add(ppt,'Title and Content');

newTitle = strcat('Step', {' '}, z,' Simulations');

replace(dataSlides,'Title', newTitle);

replace(dataSlides,'Content', imgPNG3);

clearvars -except j pL ppt directory fileList dirSize X1

end

close(ppt);

rptview(ppt);

end

ok, I understand it seems easier to work on your code , but I cannot beacuse I don't have the Report Gen Toolbox

otherwise I just tested a simplified example based on this other submission, and it seems to be pretty effective (I suppose it's not gonna be very difficult to adapt to your own needs)

exportToPPTX - File Exchange - MATLAB Central (mathworks.com)

I see it has been downloaded > 9k times (wow !)

%
%   Example 1: usage of exportToPPTX with blank presentation
%
%% Start new presentation
pptx    = exportToPPTX('', ...
    'Dimensions',[12 6], ...
    'Title','Example Presentation', ...
    'Author','MATLAB', ...
    'Subject','Automatically generated PPTX file', ...
    'Comments','This file has been automatically generated by exportToPPTX');
% Another way of setting some properties
pptx.title          = 'Demonstration Presentation';
pptx.author         = 'exportToPPTX Example';
pptx.subject        = 'Demonstration of various exportToPPTX commands';
pptx.description    = 'Description goes in here';
% Additionally background color for all slides can be set as follows:
% exportToPPTX('new','BackgroundColor',[0.5 0.5 0.5]);
%% Add some slides
figH = figure('Renderer','zbuffer'); mesh(peaks); view(0,0);
for islide=1:5,
    slideId = pptx.addSlide();
    fprintf('Added slide %d\n',slideId);
    pptx.addPicture(figH);
    pptx.addTextbox(sprintf('Slide Number %d',slideId));
    pptx.addNote(sprintf('Notes data: slide number %d',slideId));
    
    % Rotate mesh on each slide
    view(18*islide,18*islide);
end
close(figH);
%% Check current presentation
fprintf('Presentation size: %f x %f\n',pptx.dimensions);
fprintf('Number of slides: %d\n',pptx.numSlides);
%% Save presentation and close presentation -- overwrite file if it already exists
% Filename automatically checked for proper extension
newFile     = pptx.save('example');
clear pptx

hello again

seems we are now both confused here .

1/ yes my code has nothing to do with yours , it's just an example how to use the suggested FEX submission to do the job - in my eyes, with little work on your side

exportToPPTX - File Exchange - MATLAB Central (mathworks.com)

2/ no , I am not asking for more code from your side , because I cannot help you there , as I cannot run it (I don't have the ReportGenerator Toolbox)

@Mathieu NOE

Lol yea i think there was just misunderstanding.

You think this is the only effective method to resolving my issue of the for loop only plotting the last generated plot on all the PPT slides?
I'm looking at the exportToPPTX. Is there a way to add iteration so that i don't have to do "pptx.addSlide('Layout','Two Content');" continuously? I have other examples where I'll have to create 20+ slides.

Try using

drawnow

after view. It may just do the trick.

Not sure I understand what the problem is, is it that the figure is not the correct size inside powerpoint? Or that the image is not exported with the correct dimensions?

Zack Morris 2023-12-8

@Constantino Carlos Reyes-Aldasoro I'm just trying to implement a resizing command for the plots. Thy're just a little small on the PPT slides and I want to make them a little larger for easier visualization.
