I assume you mean "How do I obtain the raw data for the chart so I can
draw it?" rather than "How does the management UI draw charts?"

You can get this data from the HTTP API as documented here:

http://hg.rabbitmq.com/rabbitmq-management/raw-file/4d126a7382d7/priv/www/api/index.html

Note in particular the paragraph:
