Re: labeling axes in a ContourPlot

Because ContourPlot uses a Frame instead of Axes.

ContourPlot[Sin[x] Cos[y], {x, -Pi, Pi}, {y, -Pi, Pi},
 FrameLabel -> {"X", "Y", "Sin[x] Cos[y]"}]

A more conventional method of labeling the function might be:

ContourPlot[Sin[x] Cos[y], {x, -Pi, Pi}, {y, -Pi, Pi},
 FrameLabel -> {"X", "Y"},
 PlotLabel -> Style[Sin[x] Cos[y], 16]]

For myself, I usually make the opposite mistake of specifying a FrameLabel 
instead of AxesLabel in Graphics3D.
