I have obtained data from a instrument that is in the form of a strucutre file.

The format of the file is similar to the file created using this code:

clc;clear
% Create a sample nested structure
nestedStruct.dev1260.deviceName = 'MyDevice';
nestedStruct.dev1260.deviceID = 1260;
% Adding demodulators as an array of structures
numDemods = 1;
for i = 1:numDemods
%     nestedStruct.dev1260.demods(i).demodulatorName = ['Demodulator' num2str(i)];
    nestedStruct.dev1260.demods(i).frequency = rand(1,10); % Some frequency value (this is my x-axis)
    nestedStruct.dev1260.demods(i).amplitude = rand(1, 10); % Some amplitude values (this is my y-axis)
    nestedStruct.dev1260.demods(i).someothergarbage = rand(1,10); % Not really important
end
% Save the nested structure to a .mat file
save('nestedStructureFile.mat', 'nestedStruct');

My goal is to create a GUI that will be able to do the following:

search for the data file
allow the user to click through to which data I want to plot on my x and y axes
plot the data

The plot would look like:

plot(nestedStruct.dev1260.demods.frequency,nestedStruct.dev1260.demods.amplitude)

I have a GUI that is able to do the first step (browse the file in the current directory, which is sufficient), but I am having trouble clicking through the nested strcuture and selecting the data that I need to plotted in my x- and y- axes.

I attached the GUI code.

Any pointers are appreciated.

How do you envision step 2 would work? That is, what exactly would the GUI do as the user "clicks through" the nested structure? You may consider using a uitree instead of a listbox.
