pip install matplotlib を使用して matplotlib をインストールしようとしたところ、次のエラーが返されました。参考までに、私はWindows 7を使用しています。

このエラーを回避するために、次のダウンロードを使用してインストールを試みました: https://pypi.python.org/pypi/matplotlib/1.3.0

エラーが表示されなかったため、正しくインストールされていると想定したため、次のコード例を試しました。
import matplotlib.pyplot as plt
#import numpy as np
plt.plot([1,2,3,4],[4,7,9,12])
plt.show()
残念ながら、次のトレースバックが返されました。
Traceback (most recent call last):
File "C:\matplotlib_test.py", line 1, in <module>
import matplotlib.pyplot as plt
ImportError: No module named matplotlib.pyplot
これを正しく機能させる方法を知っている人はいますか?
