The meaning of ``aspect`` 
=============================

The aspect can be set to 'equal' (default), 'auto' or float:
- 'equal' : Keep aspect ratio of the image unchanged
- 'auto' : The aspect ratio is related to the set figsize, i.e., changing the aspect ratio
- float number f: Keep the aspect ratio f = h/w
