I think you need to consider why you want to plot negative values. The decibel scales are actually logarithmic ie all power is actually positive. Zero power corresponds to -infinity. In practice, I think your radiation pattern plot might correspond to gain (or attenuation). Just relabel your plot and change the values to positive. If you do that and the plots look familiar then you have an answer. -- Robin Becker -- http://mail.python.org/mailman/listinfo/python-list
