Hi I want to use contour for my data. Could you please tell what are these X Y and Z values used for creating contours. I tried example of pond.jmp and Cities.jmp.
From the Contour Plot help:
The Contour Plot command in the Graph menu constructs contours of a response in a rectangular coordinate system. A contour plot shows a three-dimensional surface in two dimensions. Contours delineate changes in the third dimension.
So, the X and Y correspond to the X and Y axes. The Z defines the third dimension for the contours.
The input dialog screen for the Contour Plot platform are confusing. Discussion of the complete Contour platform is available in JMP:
Help==>Books==>Essential Graphing......page 111
For the example data table "Little Pond", the columns X and Y should be moved into the "X" selection box, and the Z column moved into the "Y" selection box.
