Hi everyone,
I am very new to Python and Matplotlib, so it might be easier than I
think. I am doing something like this:
y = np.zeros((len(array1),len(array2)), dtype=float)
for i in range(len(y)):
y[i][i]= array2[i]
for i in range(len(y)):
plt.plot(array1, y[i])
#plt.savefig(filename)
plt.show()
where array1 and array2 are one dimensional, all elements with data type
float. y [i] has all elements zero except one.
My configuration is:
Executing on ('Linux', 'Lap', '2.6.31-19-generic-pae', '#56-Ubuntu SMP Thu
Jan 28 02:29:51 UTC 2010', 'i686')
Python version 2.6.4 (r264:75706, Dec 7 2009, 18:45:15)
[GCC 4.4.1]
matplotlib version 0.99.0
and I am getting following error:

angle, gc)
ValueError: cannot convert float NaN to integer
I am not sure what is going wrong, I checked the data types several times
but no clue.
Many thanks
Abhishek
