Hi,
a) ContourShading options works for me, perhaps you may upgrade the
packages from MathSource
b) for a integer number n of Contours, ContourPlot[]
will use the Min[], Max[] values of the function
and make steps between the minimum and maximim
{f1,f2}={Min[#],Max[#]} & [Flatten[data]]
and the option
Contours->Table[ c,{c,f1,f2,1/100}]
should create the contour lines with 1/100 spacing.
Regards
Jens
