Efficient Large Binary File Streaming

[kanav002]

This is my first week using Django and version 1.8 in particular. I'm trying to figure out the best way to stream a raw, large, continuously growing binary file to a plotting function that is continuously updating the last 600 bytes of the binary file. This is primarily a client side application. I have seen many streaming snippets and the StreamingHttpResponse module but am not sure which streaming method will be optimal. I'm also not sure if streaming methods are the correct approach. Can I just read the file with Python and plot in a browser window? Thanks.

Yes thank you. I went over that page and decided for my real-time binary stream I would use a FLOT chart:

However, I am trying to figure out how to get the data from a large growing binary file to the FLOT chart. Should I use StreamingHttpResponse? Should I use the django-stream package. Basically I'm looking for advice from an experienced user what works well and what doesn't. Thanks.
