Hi
Is there a function to get the coordinates to a point plotted in a figure? Im plotting two points separately in a figure, using the data cursor to get the coordinates of the two points, and then plotting a straight line between them.
To plot a line between the points i use
plot([x1,x2],[y1,y2])
with the coordinates from the data cursor.
Would be easier to use a call which extracts the coordinates after each point plotted, and then plotting the line between, and use this in my script.
Thanks

h = plot([x1,x2],[y1,y2])
x = get(h, 'xdata') % the x values
y = get(h, 'ydata') % the y values
