Dear Dennis,
Thank you for your suggestions, but I have little doubt;
res at sfXArray = x_location_of-each_point ; [*]
res at sfYArray = y_location_of-each_point ; [*]
these two resources(res at sfXArray, res at sfYArray) should be monotonically
increasing or decreasing, where in my case it is not.
What is "data" here in plotting the scatter_contour? is it a 2D array of X
and Y values (my X and Y is not any gridded data, it is unstructured
arbitrary data, with almost 40000 data points)?
Regards,
Ipsita
