对于matplotlib绘图区总是有比较强迫症的自定义要求，对于刚刚接触Python的新手来说，各种配置起来还是比较繁琐，因此开一个帖子作为注记备忘。（Jupyter-Based）
只能选择同款字体，用默认英文字体无法显示中文，用宋体的话中文能够显示但英文较丑。这里采用rcParams全局设置参数，也可使用font_manager.FontProperties()对象函数，参考matplotlib网页原文设置如下。
classmatplotlib.font_manager.FontProperties(family=None,style=None,variant=None,weight=None,stretch=None,size=None,fname=None,math_fontfamily=None)[source]Bases:object

用户希望自定义字体，即分别设置中文、英文、数学公式的字体，由于这里采用字体融合的应用将中英文混合，通过导入ttf文件以满足自定义配置的要求。（好看的图片，流程比较繁琐）
