Re: Scientific Data Frontend with Django

My grain of salt: I use django with matplotlib for a data plotting view in a status control app. It is updated every 20sec or so. With plotting embedded in my django app and called via ajax i encountered a memory leak within numpy and/or matplotlib that caused to crash the server after a week

Re: Scientific Data Frontend with Django

Hi, last week I started something in this direction. Similarly to admin.py (which describes how to administrate the data) there is a graph.py, which describes how to graph the data. It is still very rough on the edges, but you can use matplotlib in graph.py to create a plot of the data. Possibly

Re: Scientific Data Frontend with Django

Sorry, I forgot to mention the key point about codenode: it provides an interactive web page, which accepts direct Python (or Sage) commands, and includes the ability to render plots, etc. Access to a database could be provided through a Python API. --Rick On Jun 18, 10:13 pm, Rick

Re: Scientific Data Frontend with Django

Hi, Have you looked at codenode (formerly known as knoboo)? This is a distributed application with a Django frontend, and backends that can run on a variety of platforms, including Google App Engine, or even locally. --Rick [1] http://codenode.org/ On Jun 18, 1:28 pm, jordan

Re: Scientific Data Frontend with Django

I've been wanting to do a similar kind of project for a long time. Just haven't found anyone else who was interested. So, if anyone wants to try to build something like this, send me a note. Jordan On Jun 18, 2:11 pm, Vincent wrote: > Good question. Don't know. My

Re: Scientific Data Frontend with Django

Good question. Don't know. My guess is that if you just want to show the data in a view using data structures Django knows might be quicker. However, if you are going to process the data (graphs, summary stats, etc.) you might prefer to have numpy arrays to work with. Vincent On Jun 18, 2:02 

Re: Scientific Data Frontend with Django

Thanks for the link, Vincent. Is it easy to have the django view system (generic views) use a PyTables data structure, or would that be a pretty large feat by itself? Definitely worth considering, pyTables boasts great performance. Blaine On Thu, Jun 18, 2009 at 2:32 PM, Vincent

Re: Scientific Data Frontend with Django

If you have a lot of data pytables may be an option (see link below). It can store data as numpy arrays directly rather than having to convert to such an array after reading from an sql database. http://www.pytables.org Vincent On Jun 18, 1:15 pm, Blaine Booher wrote: >

Re: Scientific Data Frontend with Django

Thank you Rajesh, Vincent, Nick, and Hernan for the helpful suggestions. This is definitely a route I am going to explore. I'll post some updates to the list if anything comes out of it. Would you recommend importing the data into django models and tables, or keeping the db separate and

Re: Scientific Data Frontend with Django

I think it would be really great if you can interface with R too. There`s a library to acces to R power from Python, and then from Django. 2009/6/18 Nick Fishman > A friend of mine is using Django with matplotlib to create graphs from CSV > files, and it's turning out

Re: Scientific Data Frontend with Django

A friend of mine is using Django with matplotlib to create graphs from CSV files, and it's turning out pretty well. I haven't yet tried googlecharts, but it looks promising. The main difficulty he had with Matplotlib was transitioning to Apache/mod_python after working with the Django development

Re: Scientific Data Frontend with Django

That sounds like a great idea. Something i have been meaning to try for a while but haven't gotten around to. For a class website i did try to use matplotlib to create graphs from user provided data within django but couldn't figure out how to get it to work smoothly. Ended up using Jacobs
