Contouring categorical field

Hi all,

I want to plot, with NCL, a 2D field by contouring using cnFillOn.
However, since the field is a categorical field (values 1 to 6), it causes
problem because the interpolation
that is used by the contouring algorithm is not nearest neighbor, and it
generates in-between fictive values (e.g. field going from 1 to 6 directly,
all colors in-between are shown).

Is it possible to plot that kind of field, without using RasterFill?
Is there a way to specify the interpolation method the conpack is using?


Best regards,
