quiver plots fail when the 2D array is non-square and no 2D x,y arrays are specified. This bug looks pretty much like Bug #134919. Looks like some confusion on row/column major notation :-( import numpy import pylab x=numpy.arange(0,10)+10 y=numpy.arange(0,15) a=numpy.zeros((len(y),len(x))) a[0,:2] = 1 a[1,:2] = 3 # fails #pylab.quiver(a,a) #pylab.show() # fails #pylab.quiver(y,x,a,a) #pylab.show() # works xx,yy = numpy.meshgrid(x,y) pylab.quiver(xx,yy,a,a) pylab.show() ** Affects: matplotlib (Ubuntu) Importance: Undecided Status: New -- quiver fails for non-square arrays https://bugs.launchpad.net/bugs/405354 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
