Thanks for your reply, we tried what you suggested, but there still seems to be a bug in waterfall. The problem arises when there is data that extends far below the minimum z-axis value, like when plotting log data of an FFT result, and the z-axis has been set to -100 (dB) for z-min and 0 for z-max.
We have found no way to keep MATLAB from drawing over the bottom of the z-axes and outside of the 3-D box, except to clip the data itself (which can produce incorrect graphical results).
