Animating plot with GUI

I built a script that animated a data file by:

1. linking XDataSource and YDataSource to x and y, respectively

2. changing x and y

3. using "refreshdata" to update the plot

Worked great.

Now I'm trying to build a GUI that does this at the push of a button, but YDataSource doesn't seem to exist in the axes. My code is essentially:

    x1 = 1000;
    x2 = x1 - handles.window;
    x = x2:x1;   
    y = handles.rawD(x,1);
    plot(handles.data,x,y);
    set(handles.data,'YDataSource','y')
    set(handles.data,'XDataSource','x')

And I get the error:

??? Error using ==> set
There is no 'YDataSource' property in the 'axes' class.

When I go to the data axes properties window in the GUIDE editor, there is no YDataSource property. What's the other option?

Thanks in advance! -Ethan

h = plot(handles.data,x,y);
set(h,'YDataSource','y')
set(h,'XDataSource','x')

Note: this will only work if your x and y values are vectors. In particular if your y is not a vector, then plot() will output multiple lineseries handles, and each of them needs a different YDataSource.

Note that the variables you specified ('x' and 'y') must exist in the Base Workspace for refreshdata() to be able to find them, unless you use the 'workspace' option; see http://www.mathworks.com/help/techdoc/ref/refreshdata.html

Ah! Perfect! Thank you very much!
