matplotlib mac OSX 10.8中斷標記和座標軸標記

我的matplotlib安裝似乎是切斷刻度標記和截斷軸標籤。例如，繪圖的代碼示例具有從0到20的y軸值。垂直軸似乎只打印最左邊的數字，或者最左邊的數字用符號0,5,1,1,2打印爲0.0，5.0，10.0，15.0，20.0。垂直軸標籤打印'Amplitu'，它應該是'Amplitude，arb'改變字體大小或用窗口拉伸縮放繪圖不會改變行爲。蟒碼：matplotlib mac OSX 10.8中斷標記和座標軸標記

from numpy import arange, sin, pi 
from numpy import ma 
from matplotlib.pyplot import plot, show, title, xlabel, ylabel 

t = arange(0.0, 2.0, 0.01) 
s = 20*sin(2*pi*t) 

plot(t,s,'g') 
title("Sinewave Plot Example", fontsize=10) 
xlabel("Elapsed Time, arb", fontsize=10) 
ylabel("Amplitude, arb", fontsize=10) 
show()

這似乎是一個安裝/配置問題，而不是一個編碼問題。上述應該很好。

我已經安裝matplotlib，在Mac OSX 10.8山獅，與

這是一個known bug。一個解決方案可能是使用Python 2.7.3。
