Listboxes GUI Multiple Selection

Suppose I have two vectors with the same number of elements:

A = 1 2 3 4 5 6 7 8 9 10
B = 20 40 50 60 80 100 120 140 160 200

Suppose I want to display these in separate list boxes in a GUI - is it possible to do a table instead?

But the idea is the prompt the user to select, say, list box A for values 3 , 5 , 7, 9 and its corresponding value in B and plot them against each other.

Is this possible?

Yes, this is possible. What did you try so far? Which problem occurred?

I looked at the following page:

http://www.mathworks.com/help/matlab/creating_guis/accessing-workspace-variables-from-a-list-box-guide.html#f6-7444

but the example they provide with lb.m doesn't display the polynomials.

Try using GUIDE: http://blogs.mathworks.com/videos/category/gui-or-guide/ This is certainly possible. You might like to try a framework where you can easily modify it: MAGIC - it has most of the basic controls on there and you just replace the callbacks (which usually pop up a message or write to a label saying something like "you clicked on a button" or whatever), with your own code.

I don't have the signal processing tool box.

Signal processing toolbox is not required for anything in my response.

I am acquainted with GUIDE. As far as I have searched, you cannot load two columns in a list box. So right now I have two list boxes, however, I cannot select multiple entries within them. I was looking at the table feature but I was unable to import the data from the workspace. Essentially I have two columns of data, I only want to plot certain rows. What would you advise?

[Image Analyst]

You have to set the "max" property of the listbox equal to 2 to turn them from single selection into multiple selection.

Okay I got it. But would a table be more suitable in this case? Because then I can just extract the rows selected as opposed to clicking each entry in each listbox.

I never use tables for selecting data - just for displaying a table of numbers. If you want the user to select some I think you're better off with listboxes.

Thanks!
