Keeping with the "newbie" questions -- I'm having a hard time figuring out how to order the data -- I have x,y,z triplets, but I'm getting this error:
...increasing 'x' and 'y' values expected I saw in the documentation they should be ordered, but a) how do I do this, and b) do I need to sort by x first then y? Thanks! --j -- Jonathan A.
