Both contour and surface plot can be created from XYZ data directly. You just need to make sure that your columns are designated as X, Y, and Z. To do that, right-click on the column and choose Set As from the context menu. Then
And you also can convert your XYZ data to a matrix and then create contour or surface from it. To convert XYZ data to matrix, highlight the Z column and select Worksheet:Convert to Matrix:XYZ Gridding.
