先来了解一下wordcloud个参数的意思

• background_color='white', # 背景颜色
• max_words=1000, # 最大词数
• width=800, # 词云图片的宽度，默认400像素
• height=600, # 词云图片的高度，默认200像素
• font_path='.\simhei.TTF', # 词云指定字体文件的完整路径
• mask=back_color, # 以该参数值作图绘制词云，这个参数不为空时，width和height会被忽略
• max_font_size=80, # 词云图中最大的字体字号
• min_font_size=20, # 词云图中最小的字体字号
• mask=mask, # 词云形状，默认None，即方形图
