Hello everyone
i am creating a matlab gui which consist of a pushbutton for importing the excel file and four popup menu buttons each one will select a particular sheet from the loaded excel sheet and another poup menu in which one column of excel sheet will be loaded user will select a particular value and i want those four popup menu buttons should give the particular value from certain column corresponding to value selected from the user in fifth popup menu button then i will use those values for plotting.
i hope that i am clear
code as follows
function varargout = imgplt3d(varargin)
% IMGPLT3D MATLAB code for imgplt3d.fig
% IMGPLT3D, by itself, creates a new IMGPLT3D or raises the existing
% singleton*.
%
% H = IMGPLT3D returns the handle to a new IMGPLT3D or the handle to
% the existing singleton*.
%
% IMGPLT3D('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in IMGPLT3D.M with the given input arguments.
%
% IMGPLT3D('Property','Value',...) creates a new IMGPLT3D or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before imgplt3d_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to imgplt3d_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

Varun - when you import the data from the Excel file, you are doing
handles.data1=xlsread(filename, selectedsheet)
data1=handles.data1
set(hObject, 'data1')
where the data1 field of the handles struct is being created and set to the data from the file. This is fine but what you need to do next is to save this new field to the structure (right now, you are just updating a local copy)
handles.data1=xlsread(filename, selectedsheet)
guidata(hObject, handles); % <---- the updated handles object is now saved
The other two lines (the second which may throw an error if the data1 field is not a property of hObject) can be removed. So remove
data1=handles.data1
set(hObject, 'data1')
Then in the popupmenu6_Callback, you would access data1 via
if isfield(handles, 'data1')
item=handles.data1(item_selected, 29)
end
The line get(handles.popupmenu1, 'data1') which is throwing the error, can be removed.
