How do I prevent my figures from duplicating?

Good day.

I have the following problem. I have 1 project with 6 files (3 of type .m and 3 of type .fig, each .m corresponds to a .fig). The problem is the following: - In the file "untitled .m" I have a function (untitled_OpeningFcn) that allows to graph (just run the untitled.m) in the figure "untitled.fig", in turn in the "untitled.fig" I have a button that allows me to open "untitled3.fig" where I can add or remove coordinate points that will be added or removed from my graph; however when I remove or add points (using buttons in untitled3.fig) and call the file "untitled.m" to update the graph, a new figure "untitled.fig" is generated updated with the points but duplicated.

I wish the figure "untitled.fig" is updated with the new points, but that this figure is not duplicated. I apologize in advance if I am not fully fluent in the MATLAB language, as I am learning to program in it. I leave some lines of code for your better understanding.

• untitled.m code:

function varargout = untitled(varargin)
% UNTITLED MATLAB code for untitled.fig
%      UNTITLED, by itself, creates a new UNTITLED or raises the existing
%      singleton*.
%
%      H = UNTITLED returns the handle to a new UNTITLED or the handle to
%      the existing singleton*.
%
%      UNTITLED('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in UNTITLED.M with the given input arguments.
%
%      UNTITLED('Property','Value',...) creates a new UNTITLED or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before untitled_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to untitled_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

Attach

1. the 3 .m files and
2. the example*.mat files, and
3. 3 .fig files

with the paper clip icon so we can fix it.

Thank you very much for your help and prompt response.

I do not get the GUIs to run. I get error messages whenever I press a button:

Therefore I cannot use the debugger to find the line, which produces new figures.

Using the root object to store values is equivalent to global variables. This is a shot in your knee.

Hi. Thanks for your answer.

Look, I'm speaking out of complete ignorance, but isn't that to do with the directory where the .mat files are located?

[Pedro Guevara]

Thank you very much for your help. I managed to solve it using the function "Run" and "Close" to my Guide. It was easier than I thought, but it took me a long time to know what was the necessary function to achieve it. I leave the solution below for whoever wants to see it.

[Aghamarsh Varanasi]

Hi,

The figure 'untitiled.fig' is duplicating as a result of 'untitled' function call from the ‘Obj_Add_Callback’ function in the ‘untitled.m’ file. Whenever 'untitled' is called, a new GUI figure is created for ‘untitled.fig’.

As a work around, you can send the updated data from 'untitled3' to 'untitled' and then update the figure.

For more information on passing information between two apps, refer to this documentation. You can click on 'Try It In MATLAB' to run the example.

Hope this helps

[Pedro Guevara]

Thanks a lot. It seems that this might be the answer I need. I'm reading the documentation but to be honest the subject is very confusing. If I make any progress, I am informing you.
