Hello, I have the following script: import netCDF4 import numpy as np import matplotlib.pyplot as plt import pylab
ncfile = netCDF4.Dataset('30JUNE2012_0300UTC.cdf', 'r') dbZ = ncfile.variables['MAXDBZF'] data = dbZ[0,0] data.shape x = np.array([0,10,11]) y = np.array([0,15,16]) X,Y = np.meshgrid(x,y) u = 5*X v = 5*Y plt.figure() plt.rcParams['figure.figsize'] = (12.0,8.0) c = plt.contourf(data, 20, cmap='jet') plt.hold(True) q = plt.quiver(X,Y,u,v,angles='xy',scale=1000,color='r') p = plt.quiverkey(q,1,16.5,50,"50 m/s",coordinates='data',color='r') plt.colorbar() plt.show() and I am getting this error: TypeError: You must first set_array for mappable Can anyone provide guidance on how you overlay quiver plots on top of contours?
