[Linda_swe <po...@mt...>]

Why dont anyone answer me???

atlest give me a hint...

Ok, so i want to use the my csv as input and then plot the contour. I have
the follwing code but gives

error:list object has no attribute reshape

is using list diffrent than using numpys loadtext and then into variables
???


from matplotlib.mlab import load
import matplotlib.pyplot as plt 
import numpy as np
import csv

portfolio = csv.reader(open("file.csv", "rb"))
portfolio_list = []
portfolio_list.extend(portfolio)
lats = []
lons = []
values=[]

for data in portfolio_list:
    lats.append(data[0])
    lons.append(data[1])
    values.append(data[2])
print lats
print lons


nlats = len(lats)
nlons = len(lons)

yre = lats.reshape(nlats,nlons)
xre = lons.reshape(nlats,nlons)
zre = values.reshape(nlats,nlons)
#### later in the defined map
CT = plt.contourf(xre, yre, zre, cmap=color_map)

cbar = plt.colorbar()


plt.show()
