It is a strange object. By default an IDLgrContour is a 3-D object that uses
its data (DATA_VALUES) for its z geometry. So if you plot an unscaled
IDLgrContour object, only the parts between z = -1 and +1 (the view's
clipping limits) will be visible.

To make a planar IDLgrContour, set PLANAR=1 and GEOMZ=0. Take a look at the
documentation for these keywords and it will all become clear.
