[matplotlib-devel] web gui
Hi, could someone please point me to the latest status of the web gui? I am now in LLNL and I don't have a root access to my computer (running rhel5), and there is no Tk, nor Tkinter Python modules. I have installed femhub, so I have the whole python stack, but I don't have any gui. Mpl can save figures to a file, so at least something. But I am missing the zoom feature. I found the following cool libraries: http://www.sencha.com/ http://raphaeljs.com/ http://g.raphaeljs.com/ that work perfectly in my browser (FF3). So I wondered how hard it would be to use them as an mpl backend? All I need, I think, is just simple plotting, and zoom (+pan). I could adapt for example: lib/matplotlib/backends/backend_tkagg.py but it seems quite involved. Is there some simple thing, that would just work for me, that I could start adapting for the web gui? I would imagine that show() would launch a web server and tell the user to go to localhost:8080 or something and then the gui would be in the browser. The browser can even be opened automatically.

I doubt that you could make zoom/pan fast while going through a web interface, without substantial changes to mpl. As an alternative, can you install gtk and pygtk from tarballs, in locations you control? I haven't tried it, so I have no idea how painful it would be; but if it works, you would have a fully-functional mpl. Actually, on RH, I'm sure the gtk libraries are already there, so it would be a question of whether the -devel rpms are also installed. If so, all you need would be pygtk, and that should be easy. I presume you have already tried to get IT support to install things like pygtk. Eric I could adapt for example: lib/matplotlib/backends/backend_tkagg.py but it seems quite involved.

Re: [matplotlib-devel] web gui
Hi Ondrej, If I was in your shoes, the first thing I'd do is emit your data to plot as a json object and then plot that data using javascript with one of the libraries you've listed. Then, after gaining some familiarity with Python-json-javascript I'd think about how such an MPL backend might work. A usecase I could imagine is some Django app that uses MPL to plot stuff into a javascript canvas element complete with zooming and so on. I think there are a lot of open questions in this domain... For example, presumably one doesn't want the server involved when the client browser zooms. But then if you implement something that allows the client browser to zoom without the server MPL process, you're no longer using the normal MPL callback system. So, interactivity would probably be different than in the traditional backends. You could also start with the svg backend, as browsers do render svg. -Andrew Ondrej Certik wrote: Hi, could someone please point me to the latest status of the web gui?

Re: [matplotlib-devel] web gui
I have a student here trying to make a webapp for data reduction. To add interactivity, we've been using the FLOT package, and may later consider protovis. We had thought about making a javascript backend for MPL, but to just get something running, we went with FLOT for the time being...We're using EXTJS as the web framework (it's a bit heavy, but has a rich widget toolkit and documentation). We use Django on the backend and Orbited to deal with some communications between the browser and the server (for example if we get new data from an instrument and want to update it on the server and update plots that are viewing that data..). Over the next couple of weeks (with the arrival of another student), we will be working more with the plotting aspect of the project (adding legends, zooming, etc). Also, for other parts of the app, we're just using the HTML5 canvas...I'd be happy to work on making the plotting addons as generic as possible so they can be used outside of our problem domain. What I'm not sure is whether one wants to truly use MPL as a backend, or rather to use the MPL philosophy of a javascript package.

Re: [matplotlib-devel] web gui
www.reflectometry.org/flot/examples has some examples with zooming for flot. These seem ok for speed using firefox...How many data points?
