How to get the values on a given axis of a given figure ?

Hello,

I'm doing a little re-labeling function on an existing figure and I need to get the number of values on the X axis. The data plotted on the figure is supposed to be unknown, and I was wondering if it was possible to more generally retrieve the data values from the axes of any given figure.

Thank you very much for you help

all the best

L.

 x=0:0.1:10;
 y=sin(x)
 plot(x,y)

%select a plot in your figure, then run this:

xdata=get(gco,'Xdata') % to get X-axis data
Ydata=get(gco,'Ydata') % to get Y-axis data
