自己的代码试验：
生成GBDT的特征重要性排序图

from pylab import mpl
mpl.rcParams['font.sans-serif'] = ['SimHei'] # 指定默认字体/Microsoft YaHei
mpl.rcParams['axes.unicode_minus'] = False # 解决保存图像是负号'-'显示为方块的问问题

gbdt_importance = model.feature_importances_
index = X_fmt.columns
gbdt_feature_importance = pd.DataFrame(gbdt_importance.T, index=index,columns=['score']).sort_values(by='score', ascending=True)

# 水平条形图绘制
a = gbdt_feature_importance.plot(kind='barh', legend=False,figsize=(10,9),fontsize=13,width=0.6,linewidth=None,edgecolor = 'white')
a.spines['top'].set_alpha(0.01)
a.spines['right'].set_alpha(0.01)

plt.show()![在这里插入图片描述](https://www.www.zyiz.net/i/ll/?i=84865fa32a364476bdccad6e46b6ea31.png?,type_ZHJvaWRzYW5zZmFsbGJhY2s,shadow_50,text_Q1NETiBA5LyN5bKz5YeM,size_20,color_FFFFFF,t_70,g_se,x_16#pic_center)
