# Pie Chart

# plt.pie( data list[,選擇參數列])

# 可用參數如下 :

# labels : 每一個項目標題組成的list

# colors : 每一個項目顏色組成的list

# explode : 每一個凸出數值組成的串列 0表示未凸出 數值越大凸出越明顯

# labeldistance : 項目標題與圓心的距離是半徑的多少倍 (i.e. 每一子塊標題與圓心距離)

# autopct : 項目百分比的格式 ( %格式%% 例如: %2.1f%%)

# shadow : T/F值 True表示圖形有陰影

# startangle : 繪圖起始角度，逆時針跑

# pctdistance : 百分比文字與圓心的距離是半徑的多少倍
