I have a very dense scatter plot with a coloured bar and the points are colour coded according to the value shown in the colour bar. I want to connect the points which bear the same z value. Please help.

Thanks for your answer. I am receiving this error while applying the peaks function.
"Error using repmat
Requested 501501x501501 (1873.8GB) array exceeds maximum array size preference (7.9GB). This might cause MATLAB to become
unresponsive."
What should I do?

I have shown you an example of how you can do it using contour. peaks is used to create demo data. You need to use contour for your data after reading the documentation.
