How to stop popping up of plot figures unnecessarily in Matlab app designer?

My GUI desgned on MATLAB app designer is working perfectly. However, at one stage it is popping out a separate figure which should not appear.

How I can stop that plot figure from popping out?

Answer 1

I did it using the following command,

figure('Visible', 'off');

Answer 2

If it is due to a plot function, you need to define the uiaxes for the plot. such as:

plot(app.UIAxes,x,y)

Actually when I am calling the following program to run then the attached figure (1.png) is popping out, which I want to stop.

function [array, array_C, param] = outline_BF(microwells, fudgefactor)

% Program for creating outline on 3D structrues
param = zeros(25,6); array = cell(25,1); array_C = cell(25,1);

for b = 1:25
    
% Outline for bright field..................................................
    image = microwells{b};
    [~,threshold] = edge(image,'Sobel');
    BWO = imbinarize(imadjust(image), threshold*fudgefactor); 
    BW = imcomplement(BWO);
    seD = strel('diamond',9); 
    BW3 = imdilate(BW,seD); 
    BW4 = imfill(BW3,'holes');
    BWM = imerode(BW4,seD); % addition new
    BW5 = imerode(BWM,ones(17));
    BW6 = imdilate(BW5,ones(17));
    BWoutline = bwperim(BW6, 8);
    temp = imoverlay(image,BWoutline,'cyan');
    bound = []; boundary = []; intensity = [];
    [bound,I,~,~] = bwboundaries(BW6,'noholes');
    %figure,imshow(image)
    bound_S = rem_edge(I);
    A = 0; 
    black = logical(zeros(size(BW6))); 
  
    if ~isempty(bound_S)
        for k=1:length(bound_S)
            boundary = bound{bound_S(k)};
            Par = blob_parameters(boundary(:,2), boundary(:,1));
%             labeledImage = logical(BW6);
            if Par(1) > A
                param(b,1:5) = Par;
                plot(boundary(:,2), boundary(:,1),'r-', 'LineWidth', 1);     % plot boundaries
                A = Par(1);
                BW7 = select_bound(black, boundary);
                BW7f = imfill(BW7,'holes');
                intensity = regionprops(BW7f, image, 'MeanIntensity');
                param(b,6) = intensity.MeanIntensity;
            end
        end
    else
        param(b,:) = [NaN NaN NaN NaN NaN NaN];
        BW7f = BW6;
    end
    
    BWoutline2 = bwperim(BW7f);
    array{b} = imoverlay(temp,BWoutline2,'red');
    
 % Canny for bright field...................................................
    array_C{b} = edge(image, 'Canny');
end

change

plot(boundary(:,2), boundary(:,1),'r-', 'LineWidth', 1);

to

plot(app.UIAxes,boundary(:,2), boundary(:,1),'r-', 'LineWidth', 1);

[Amlan basu]

I don't want the plot to appear anywhere.

[Kevin Holly]

In that case, remove the line completely.

[Amlan basu]

This worked,

 figure('Visible', 'off'); % I put this before and it worked 
 
 BWoutline = bwperim(BW6, 8);

There is no need to draw the plot if you are not using it. Unless you want to save the figure without displaying it. Could speed up your program by commenting it out.
