Solution of running error reporting attributeerror: ‘rectangle’ object has no property ‘normalized’

Have a problem

When running the code, the following error prompt appears:

AttributeError:'Rectangle' object has no property 'normed'

resolvent

The reason is that the library has been updated and there is no such attribute. Delete the normal in the code (no error, but it seems that it can’t be drawn)

Replace the normal attribute in the code with density , and add an attribute stacked = true .

Thank you for your comments.
