I think since its a joint histogram, you need to have equal no. of data points and bins in both x and y. On Fri, Jul 20, 2012 at 5:11 PM, Andreas Hilboll li...@hilboll.de wrote: Hi, I have a problem using histogram2d: from numpy import linspace, histogram2d bins_x = linspace(-180.,

[Numpy-discussion] numpy.complex

2012-07-20 Thread OC
The syntax numpy.complex(A) seems to be the most natural and obvious thing a user would want for casting an array A to complex values. Expressions like A.astype(complex), array(A, dtype=complex), numpy.complex128(A) are less obvious, especially the last two ones, which look a bit far-fetched.
