Hi,
The best option is to use the Contour Plot platform under the Graph menu with your data organized as X, Y, and Z columns
Contour Plot(
X( :X, :Y ),
Y( :Z ),
Show Data Points( 0 ),
Fill Areas( 1 ),
Label Contours( 0 ),
Transform( "None" ),
Color Theme( "Jet" ),
Specify Contours( Min( -100 ), Max( 150 ), N( 6 ) ),
);
OUPUT:
Where Z = X + Y (as an example)
Best,
TS
