ListOfImageNames = get(handles.lstImageList, 'string');
numberOfItems = length(ListOfImageNames);
% Get the index(es) of the entry they've selected.

vedesh - in the pushbutton callback, you would use the handles structure to get the selections from the two dropdown menus. Your code could look something like the following

function pushbutton1_Callback(hObject, eventdata, handles) 
% get the selection from the first drop down menu
popup1List = get(handles.popup1,'String'); % get the list of items of popup1
popup1Index = get(handles.popup1,'Value'); % get the index of the selected item of popup1
popup1Value = popup1List{idx};             % get the value of the selected item of popup1
% get the selection from the second drop down menu
popup2List = get(handles.popup2,'String'); % get the list of items of popup2
popup2Index = get(handles.popup2,'Value'); % get the index of the selected item of popup2
popup2Value = popup2List{idx};             % get the value of the selected item of popup2
% note that popup1Value and popup2Value are strings so you may need to convert to numbers is
% applicable
% do whatever work you need to and draw line on axes

MATLAB: [GUI] How do you get only one element in a listbox

You have to read in the whole thing anyway. Then get the value property and use that to index into the string.

listboxItems = get(handles.listbox1, 'string');
selectedItems = get(handles.listbox1, 'value');
selectedItem = listboxItems(selectedItems);
