Hello all,<br><br>I'm having a difficult time viewing what must be the simplest data set possible. I have a csv file that includes 3 columns of numbers which I'd like to view as 'elevation' type data: 1st two columns give x & y coord (regular, though step-size for x and y are different), and 3rd column gives a height (the data is actually error vs. 2 different params). I can open the file, and see that it has read the columns of data correctly, but can't get a plot of this surface.<br><br>Seems this should be simple to view, but after blundering around the interface for too long, it is not as obvious as one would hope.<br><br>Thanks,<br>Thomas Blom<br><p>
