Hello everybody, is there any possibility how to get the coordinates of the isolines generated by the surf function? I'd like to define a region which is enclosed by a specific isoline value. Thank you in advance, Tom

There are no isolines on a surf. Do you mean contour? If so, you can capture them as the second output from contour. They are in a weird format, so read the doc, but they are there.

Thanks for your answer. I really meant the surf function. I thougth that I can call those color lines as isolines since one color represent one value. But it does not mind how we will call them. For me it is important somehow find out coordinates of individual lines/values. May be any other function is more suitable for this issue, but I do not know which one it is.
