MATLAB CODE FOR NEXT PAGE IN GUI

Hi, I made a GUI program where I examine graphs from measured data in a text file. The GUI works as follows: The first title page, after clicking on the "NAJÍT DATA" button, I select a text file and graphs are displayed including all the functions that I have programmed.

However, my problem...

I can't fit all the information I need in the first window. Therefore, I would like to add a button called "MAP" that will launch another (second) GUI window (page). I would like to use code to insert a map, other graphs, etc. into this window. And at the same time I'd like to keep the first GUI window with graphs etc.

Is this possible? I've been puzzling over this for two days now and can't get it to work. Any advice would be greatly appreciated!!

For testing, below is the code of my program with an attached text document and needed picture.

Answer 1

[Walter Roberson]

In every case in which you construct a graphics object, you should specify the parent object to insert the new object into, if possible.

Your lines such as

L5=line(t,z, 'color', 'green', 'linewidth',1, 'parent', ax3)

are a good start on that; you just need to take it further. For example,

ax4=axes('units', 'norm', 'position', [0.6 0.73 0.39 0.24], 'color', [0.7 0.7 0.7], 'xlim', [0 inf],'ylim', [12 16], 'tag', 'axes4');

should be told which graphics container the axes should be placed into.

In every case in which you use operations such as grid on you should specify the axes the operation applies to.

In every call to legend(), specify either the target axes or else the subset of objects to work with.

For calls such as

findobj('tag','axes1')

you should specify the starting object to descend from -- often a figure object but could be more specific. The exception to this would be if you are willing to ensure that your tags are going to be unique between figures -- no axes1 in both the first and second figures for example. Unless, that is, you are willing to have all axes with the same tag be updated simultaneously.

            uicontrol('units', 'norm', 'position', [0.86 0.25 0.13 0.03], 'style', 'push', 'tag', '0-5', 'string',...
                'ČASOVÝ ÚSEK T=0-5 [s]', 'fontsize', 10, 'foregroundcolor', [0 0 0],'backgroundcolor', [0.9290, 0.6940, 0.1250], 'callback', 'gui_LP_01 0-5');          

Reminder: when you specify a Callback for a graphic object in the form of a string() object or a character vector, then the text will be executed in the context of the base workspace, and any functions named must be publicly available. The above uicontrol callback would not work if gui_LP_01 were a private function inside another function, for example. And the text will not have access to any local variables in the workspace of the function that established the callback text.

Thank you very much for the valuable advice, I will look into it and try to improve it. However, at first glance it is not clear to me how this information will help me to create another window in my GUI in which I can have other functions programmed (such as more graphs, maps etc)

[Walter Roberson]

There are two challenges to multiple windows:

• code getting them confused, especially taking actions on the "wrong" window. Parenting everything solves this (except for a couple of graphics functions that you have to hack the return structures for.)
• separating data for the windows but also sharing it when needed. The usual data sharing guidelines apply. If you were using GUIDE and the guidata() helpers, I would have given an additional hint.

As far as MATLAB is concerned, as "GUI" is a figure object that has behaviour attached to it. MATLAB does not have any such thing as a "graphics only" window. Even simple plot(1:20) output has behaviour attached to it, such as zoom behaviour. Your code can open and close windows as needed, and make them invisible or visible as needed. Nothing special needs to be done such as "tell the second gui, close yourself": you just delete() the graphics object handle, same as if you were working with the first window.

It is often convenient to separate out local variables for each "gui" to make it easier to write the code for each gui mostly independently without worrying about whether the same variable name happened to already be used for a different gui. But that is not mandatory.
