HOW PLOT LISTBOX SELECTION

I have a list box with a number of different options to plot (e.g. Fx, Fy, Mz). When one is selected, I want to plot the related variable which is stored in the workspace on the axes (axes1_graph) that i have on my GUI. How can this be achievied?

Thank you

What exactly does "stored in the workspace" mean? Which workspace? Any function has its own one. It would be smarter and safer to store the data in the UserData of the figure or the listbox itself.

How do you "select" values of a listbox? Do you mean a popup menu? If so, did you search in this forum already, where this topic has been discussed dozens of times? Did you check Matt's examples already?

STored in the workspace: as in Fx is a defined variable I'm using 2010 matlab and listbox is what it is called.

@Krystina: Of course I'm able to guess the details, but it would be more efficient, if you provide the complete information. Where did you define the variable? Inside a function, a script or in the base workspace (such that you can display them in the command window)? How do you "select" a value of a listbox? Single click, double click, slect with the mouse and press a "Display" button?

Guessing the details of a question causes differences between the given and the needed answer. Please be as precise as possible. E.g. posting a piece of code, which reproduces the problem, is always a good idea. It might matter, if your GUI has been created programatically or using GUIDE. Explaining details like "axes1_graph" is recommended also: The meaning might be obvious for you, and it might be possible to guess what this string could be, but a good question does either define or omit such details. Thanks.

the variables in the list are defined in the editor, using values which are imported from an excel sheet. An example is as such: Fx(i,j) = (D*sin(C*atan(B*X1-E*(B*X1-atan(B*X1)))))+Sv;

I used GUIDE to create the GUI. To select something from the listbox you single click it and it highlights.

The automatic code generated for the list box is as such:

% --- Executes during object creation, after setting all properties.

function listbox1_CreateFcn(hObject, eventdata, handles)

% hObject handle to listbox1 (see GCBO)

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

% handles empty - handles not created until after all CreateFcns called

if ispc && isequal(get(hObject,'BackgroundColor'), get

(0,'defaultUicontrolBackgroundColor'))

    set(hObject,'BackgroundColor','white');

end

axes_graph1 is the tag for my axes in my gui.

hope this helps.

thanks for your time
