   Implementation steps: define a new show method, and then rewrite plt.show
   ```
   def show_plog(fmt="png", width="auto", height="auto",
                       **kwargs):
     """Matplotlib show function
     """
     import matplotlib.pyplot as p
     if fmt == "png":
       img = BytesIO()
       p.savefig(img, format=fmt)
       img_str = b"data:image/png;base64,"
       img_str += base64.b64encode(img.getvalue().strip())
       img_tag = "<img src={img} style='width={width};height:{height}'>"
       # Decoding is necessary for Python 3 compability
       img_str = img_str.decode("utf-8")
       img_str = img_tag.format(img=img_str, width=width, height=height)
     elif fmt == "svg":
       img = StringIO()
       p.savefig(img, format=fmt)
       img_str = img.getvalue()
     else:
       raise ValueError("fmt must be 'png' or 'svg'")
     html = "<div style='width:{width};height:{height}'>{img}<div>"
     #print(html.format(width=width, height=height, img=img_str))
     intp.showHTML(html.format(width=width, height=height, img=img_str))
     img.close()
   
   plt.show=show_plog
   plt.show()
   ```
