Thanks! BTW would you consider changing the definition of spy(2) as shown below, so that one could specify what 'to be a zero' means? r. def spy(self, Z, precision = None, marker='s', markersize=10, **kwargs): if hasattr(Z, 'tocoo'): c = Z.tocoo() if precision is None: x = c.row y = c.col z = c.data else: ii = where( abs( c.data ) > precision )[0] x = c.row[ii] y = c.col[ii] z = c.data[ii] else: if precision is None: x,y,z = matplotlib.mlab.get_xyz_where(Z, Z != 0) else: x,y,z = matplotlib.mlab.get_xyz_where(Z, abs( Z ) > precision) return self.plot(x+0.5,y+0.5, linestyle='None', marker=marker,markersize=markersize, **kwargs) ------------------------------------------------------------------------- Take Surveys.
