Hope that everyone is doing great so far.

So basically, in this gui, I am trying to plot certain set of data, based on the output of the "Types" popupmenue.

function varargout = demo9(varargin)
% DEMO9 MATLAB code for demo9.fig
%      DEMO9, by itself, creates a new DEMO9 or raises the existing
%      singleton*.
%
%      H = DEMO9 returns the handle to a new DEMO9 or the handle to
%      the existing singleton*.
%
%      DEMO9('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in DEMO9.M with the given input arguments.
%
%      DEMO9('Property','Value',...) creates a new DEMO9 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before demo9_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to demo9_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

so basicaly, whatever option I choose in this popupmenu...

function Cases_Callback(hObject, eventdata, handles)

% hObject handle to Cases (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

% Hints: contents = cellstr(get(hObject,'String')) returns Cases contents as cell array

% contents{get(hObject,'Value')} returns selected item from Cases

switch get(handles.Cases,'Value')

case 1

set(handles.Condition,'string',' ');

set(handles.Types,'Value',1)

case 2

set(handles.Condition, 'string', 'Temperature');

a='Select Type'; b= 'T5'; c= 'T10'; d='T15';

e=char(a,b,c,d)

set(handles.Types,'Value',1)

set(handles.Types, 'string', e)

case 3

set(handles.Condition, 'string', 'Temperature');

a='Select Type'; b= 'T5'; c= 'T10'; d='T15';

e=char(a,b,c,d)

set(handles.Types, 'string', e)

set(handles.Types,'Value',1)

case 4

set(handles.Condition, 'string', 'Pressure');

a='Select Type'; b= 'P1'; c= 'P2'; d='P5';

e=char(a,b,c,d)

set(handles.Types, 'string', e)

set(handles.Types,'Value',1)

otherwise

end

is going to add certain string to this popupmenu....

function Types_Callback(hObject, eventdata, handles)

% hObject handle to Types (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

% Hints: contents = cellstr(get(hObject,'String')) returns Types contents as cell array

% contents{get(hObject,'Value')} returns selected item from Types

I would like to plot some data based on the selection I make in the last popupmenu. in this pushbutton....

function plot_Callback(hObject, eventdata, handles)

% hObject handle to plot (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

I hope this gives u a better idea..

the question is how to retrieve data from a popupmenu to a push button, to plot these data?

Adam Danz 2019-7-31

popupmenu.Value stores the popup menu selection where "popupmenu" is the handle to your popup menu. You can also get that through handles.popupmenu.Value.

Assuming you want to plot the data collected from ‘handles.Types’ popupmenu, store 'Value’ property of ‘handles.Types' from ‘Types_Callback’ and use it in ‘Plot_Callback’.
