Hi, After trying for a while to get the contour line 1 to be shown for 0<x<~0.5 and 0<y<-0.5 with ContourPlot[Cos[x*y], {x, -Pi, Pi}, {y, -Pi, Pi}] It appears ContourPlot has a bug. (The displayed contour line 1 is not symmetric in the vicinity of x=0, y=0) I wonder if its my system or others noticed this. I am sending it to Mathematica Bugs for them to confirm. Cheers ...
