MATLAB: Use UICONTROL for listbox

listboxuicontrol

I need to use uicontrol to create a listbox. Instead of changing the variables each time the script is executed, I want to be able to change it on a GUI screen. So my list is composed of 5 variables:

mass
velocity
time
acceleration
speed

and these 5 variables have data.

Thanks,

Amanda

yourcell={'mass','velocity','time','acceleration','speed'}
uicontrol('Style', 'listbox','Position',[100 100 200 200],...
'string',yourcell,'Callback',@yourfunction)
%---------------add your function---------------------
   function yourfunction(hObj,event)
v=get(hObj,'value')
%do
end

Do you mean like this:

function learnlists
clc;
format compact;
format long;
figure;
yourcell={'mass','velocity','time','acceleration','speed'}
% Create first listbox.
uicontrol('Style', 'listbox','Position',[100 100 200 200],...
  'string',yourcell,'Callback',@measurements)
% Create second listbox.
uicontrol('Style', 'listbox','Position',[300 100 200 200],...
  'string',yourcell,'Callback',@measurements)
function [out] = measurements(handleToParentControl,evnt)
mass = [ 23 45 44];
velocity = [34 53 32];
time = [1 2 3];
acceleration = [32 22 12];
speed = [12 33 44];
selectedItem = get(handleToParentControl,'value');
% Print selected array to command window:
switch selectedItem
  case 1
    mass
  case 2
    velocity
  case 3
    time
  case 4
    acceleration
  case 5
    speed
end

I suggest that instead of having your measurements function as a callback, that you use something like

function [out] = measurements
  mesnames = {'mass', 'velocity', 'time', 'acceleration', 'speed'};
  mesvals = {[ 23 45 44], [34 53 32], [1 2 3], [32 22 12], [12 33 44]};
  out = struct('name', mesnames, 'value', mesvals);

Then

handles.measurements = measurements();
handles.list1 = uicontrol('Style', 'listbox','Position',[100 100 200 200],...
    'string',yourcell, 'Callback',@select_n_plot);
handles.list2 = uicontrol('Style', 'listbox','Position',[300 100 200 200],...
    'string',yourcell, 'Callback', @select_n_plot);
guidata(gcf, handles);
function select_n_plot(hObject, event)
  handles = guidata(hObject);
    list1val = get(handles.list1,'Value');
    list1var = handles.measurements(list1val);
    list1varname = list1var.name;
    list1varval = list1var.value;

and likewise for list2. After that, plot list1varval against list2varval and label with list1varname and list2varname
