matplotlib 画饼图

有个瑕疵，某一块儿比例过小时，文字会重叠。

def pizza(data,labs,title):
    import matplotlib
    import matplotlib.pyplot as plt
    cols=[col for col in matplotlib.colors.TABLEAU_COLORS][:len(data)]
    plt.pie(data,labels=labs,colors=cols,startangle=90,
            textprops={'fontsize':10,'color':'k'},shadow= False,autopct='%1.2f%%')
    plt.legend(loc="upper right",fontsize=10,bbox_to_anchor=(1.1,1.05),borderaxespad=0.1)
    plt.title(title)
    plt.show()

pizza([305,9695,1000],["F","HQ","samll"],"pizaa")
