[Matplotlib-users] bisecting triangulation
Hi,
I have set of points in a plane and make triplot:
subplot(121)
plot(points[:,0], points[:,1], 'o')
title('Set of points')
subplot(122)
triplot(points[:,0], points[:,1])
title('Triangulation')
result: http://i.imgur.com/1LG4fxC.png
Does anyone know how to extract just the lines describing each circumscribed
circle in this example?
Perhaps by using Delaunay from scipy.spatial?
Just to inform you, I want to do this through triangulation and above example
is trivial that can be solved differently, while real problem doesn't contain
circles...
Thanks

[Matplotlib-users] Reports from SciPy 2013
SciPy 2013 was a great success. I didn't get good headcount at the matplotlib BOF, but it was a good number, and we had 15 participants at various points during the sprints. It was nice to see the diversity of experience with matplotlib at the sprints, and I hope we oldtimers were helpful to the newtimers getting started so they can continue to contribute in the future. It was also great to put some faces to many of the talented names I've been seeing on github and the mailing list lately. I've summarized the matplotlib BOF as well as the sprint. I've also gone ahead and created MEP placeholders and issues for the major themes discussed. https://github.com/matplotlib/matplotlib/wiki/Scipy-2013-BOF-Notes https://github.com/matplotlib/matplotlib/wiki/Scipy-2013-sprinting-notes Both of these documents are based on the realtime etherpad notes we made during the sessions, and on some of my own recollection, which is known to be incomplete or incorrect on occasion. If I missed something, or you feel something isn't expressed in the right light, feel free to edit the wiki, but we should keep further discussion on the mailing list, github issues or other channels. It would also be great to have volunteers to help write a MEP or two based on the BOF discussion. Thanks again. It was really nice to meet all of you!

I'm a beginner at matplotlib, but I do know what Bollinger bands are, and I'd suggest your best approach is to take a look at the matplotlib demo gallery here: http://matplotlib.org/examples in particular, study the code for the fifth example from the top here: http://matplotlib.org/examples/pylab_examples/plotfile_demo.html which implements a plot of Open, High. Low, and Closing prices. I'm assuming you know enough math to implement a Bollinger band version of a moving average, and can just substitute it for the code that plots the extra lines on the example.

[Matplotlib-users] In Memoriam, John D. Hunter III: 1968-2012
Hi all, after John's untimely passing we had a memorial service in Chicago, but only a few on these lists were able to attend. At last week's scipy conference I read a slightly edited version of the eulogy from that memorial service, and I figured some of you might be interested if you missed the conference: http://blog.fperez.org/2013/07/in-memoriam-john-d-hunter-iii-1968-2012.html Cheers, f -- Fernando Perez (@fperez_org; http://fperez.org) fperez.net-at-gmail: mailing lists only (I ignore this when swamped!) fernando.perez-at-berkeley: contact me here for any direct mail -- This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev ___ Matplotlib-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/matplotlib-users

One of the things that I learned when no one responds with a specific answer but shown the direction is that I am given an opportunity to learn and work by myself. I really appreciate your time and will start working on the example you have cited. In fact, I did get a complete Bollinger bands script however, I will start working on the line you have shown; it may open up new avenues. Regards.
