聚类分析树状图的初探

参考官方文档：https://docs.scipy.org/doc/scipy/reference/index.html

　　此次使用聚类分析是因为文章需要，然后参考官方文档简单制作满足分析要求的树状图。

　　因为到时候在A4纸上需要把三个图排版一下，所以在输出的时候就把图片设置的比较小。

 5 plt.rcParams['font.sans-serif'] = ['SimHei'] #解决中文显示
 6 plt.rcParams['axes.unicode_minus'] = False #解决符号无法显示
 7 #设置颜色
 8 #hierarchy.set_link_color_palette(['m', 'c', 'y', 'k'])

10 df = pd.read_excel('品种日产量聚类.xlsx',sheet_name='zaoju')
