- select the second plot then click "more proprieties" you will find your data in xdata and ydata
- do the same to the third plot
Transfer data from a figure to variable

Hi,
I'm using Matlab Simulink to simulate the behavior of a electric circuit.
I obtain the average transfer function by using "averaging spectrum analyzer" block. What i need to do is to obtain the data of this average transfer function. I mean, i want to obtain in a vector x the range of frequency and in a vector y the range of gain.
How can i do it?
Thanks in advanced, Néstor

open axes proprieties of your figure,then click "more proprieties"
be sur that you select the plot (not only the box)
x=get(gco,'XData');y=get(gco,'YData');

Néstor, be sur to click on the plot, not just on the windows, you will see your points highlighted. when you are done go to matlab command and write
x=get(gco,'XData');y=get(gco,'YData');

to do it without interacting with the mouse at all you can get to the data through the children of the axes handle: e.g.
figure;
plot ( magic(10) );
axes_children = get ( gca, 'children' );
axes_lines = findobj ( axes_children, 'type', 'line' );
xdata = get ( axes_lines, 'xdata' )
ydata = get ( axes_lines, 'ydata' )

It was said in his question. that's what "averaging spectrum analyzer" do

Ok - I've never used that so wouldn't know... You learn something new everyday :)
