Hello i have been working on my project but currently i have been stuck on this problem where i cant plot to my UIAxes using my GUI program (app designer) here is my code :
(function 1)
rawdata = uigetfile('*.mat','Select the MATLAB code files', 'MultiSelect', 'on');
varlist = who('-file',rawdata);
app.ListBox.Items = varlist(1);
setappdata(0,'onedata',varlist);
in this function i should upload my .mat file in so i can plot in UIAxes in function 2 :
value = app.StateButton.Value;
x=getappdata(0,'onedata');
plot(app.UIAxes,x);
but each time it tells me
Error using plot
Invalid first data argument.
please help.

x=getappdata(0,'onedata');
Gives you the cell array output from the call to who. You can't plot that in any axes.

You have to load variables from the .mat file, not just reference the cellstr representation of the variable names. I'm sure there are lots of examples on MATLAB Answers for plotting from a .mat file.
