Accepted Answer. The problem is your data goes from [-6.5 8]. The 16 **contour** lines have been drawn for that. Then when you call caxis, you get rid of any color distinction above 2 or below -2 (>2 all have same color, <-2 all have same color). This does not affect where the actual contor lines go, though. Just the range of values used to assign.
