[Matplotlib-users] ANN: Michael Droettboom, matplotlib lead developer
It is a great honor for me to announce that Michael Droettboom has agreed to take on the role of lead developer of matplotlib. Since Michael joined the project in 2007, he has been responsible for much of the code that brought matplotlib from being an excellent tool to a world class one. No one in the world understands the code from the inside out like he does, and many of his contributions, while often unseen at the surface, have laid the foundation for matplotlib to reach further into the wild and wonderful things it can now do. To name a few of his contributions: generic, optimized caching transformations; dramatic backend simplification and rationalization; countless optimizations; implementation of Knuth mathtex layouts; python3 support, and dolphins! I like to tell people Michael codes with the force of ten men, and he's an incredible asset to our team. My role has been significantly diminished of late -- although I have been the nominal lead developer, in practice I have been a release manager. Unfortunately, I need to take some time to focus on family health issues, but will continue to follow development and make contributions as I can. We'll be looking for a release manager soon, and if you are interested in stepping up, we'll welcome the effort. We have a wonderful distributed development team using github pull requests, and the line between core developers, project leaders and plain-ole contributers is blurry. But I think it helps to have someone thinking about the project as a whole, who is willing and able to make decisions when necessary, and no one is better suited to doing this than Michael. I also extend my heartfelt thanks to Perry Greenfield and STScI. They have been supporting matplotlib since 2004 with ideas, code and developer resources. They employ Michael currently, and are part of the reason why he is able to take on the leadership of this large project. Michael, many thanks. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Announcement: mpltools 0.1
==
mpltools is a package of tools for matplotlib. For the most part, these
tools are only loosely-connected in functionality, but there are two that
may prove particularly useful:
Styles and plot2rst
---
Tony, is there a way to switch styles rather than chain them. Eg, if I
do:
import mpltools.style as style
style.use('ieee.transaction')
...make_a_plot_...
style.use('ggplot')
...make_a_plot_...
I seem to get the chained behavior of the second style updating the first.
I'd like to use this in a demo context where I can illustrate the styles
separately, so it would be nice to go back to the defaults.
Interestingly, I tried to do:
import matplotlib
matplotlib.rc_file_defaults()
plt.close('all')
hist(rand(1), 100)
but that simply stopped figures from raising all together (I don't think
this is related to mpltools, but to something funny going on on my system).
So in summary, it would be nice to be able to do something like:
style.use('default')
or:
style.reset()
which would take you back to a clean slate.

Neither. cbook is really meant more for the devs. Half of it is converter functions that are probably completely unneeded now, while the other half is the callback registry. I disagree that cbook is meant for devs. I initially used cbook as a place to put neat recipes from the python cookbook. It has grown a bit from there. The stuff that is in there like is_string_like is generically useful. The converters are used by the rec2* funcs, eg the rec2excel function in the exceltools toolkit. I use these extensively. Luckily, the module is called cbook.py, so one could pretend that it isn't cookbook but rather callback book... Meanwhile, mlab's own documentation says: Numerical python functions written for compatability with MATLAB commands with the same names. So, unless someone can find out if MATLAB has some sort of equivalent functionality hidden away somewhere, it doesn't belong there either. Or better, we change the docstring.

successful files get created, but then always on the same pass it does
this. The full traceback is here:
I wonder if the solution is as simple as doing font caching at the class

The renderer handles all the drawing primitives using a graphics
context instance that controls the colors/styles

def __init__(self, width, height, dpi):

RendererBase.__init__(self)
self.texd = maxdict(50) # a cache of tex image rasters
self._fontd = maxdict(50)

class RendererAgg(RendererBase):
The renderer handles all the drawing primitives using a graphics
context instance that controls the colors/styles

_fontd = maxdict(50)
texd = maxdict(50) # a cache of tex image rasters

RendererBase.__init__(self)
Does anyone see an issue with doing this caching at the class level? If
this works, we should have *many* fewer font files parsed.
w/o modifying the src code, a related way to test this idea is to reuse the
same figure instance and clear it at the start of the loop. Ie, rather than
for i in range(N):
fig = plt.figure()
plot_something
fig.savefig(...)
do
fig = plt.figure()
for i in range(N):
fig.clf()
plot_something
fig.savefig(...)
I would try the latter first, and if that works I would appreciate it if
you test the src code modification unless someone chimes in and tells us
that is a really bad idea.

In the code as you've written it, the is in the global namespace, and so
your pick event handlers can see that variable. So you could write:
def pick_rlines(art,mouseevent):
button = mouseevent.button
key = mouseevent.key
the.wsf.nnn = 4 # the is in the global namespace
But a cleaner design would be to make the pick handler a class method of
class BBB, eg
class BBB:
def __init__(self):
self.fig = blah_blah...
self.fig.canvas.mpl_connect('pick_event', self.pick_handler)
self.wsf = blah_blah...
def pick_handler(self, artist, event):

Re: [Matplotlib-users] Has nxutils been removed from mpl?
On Thu, Mar 8, 2012 at 10:32 AM, Benjamin Root ben.r...@ou.edu wrote: +1 as well. I just took another look at the Path object and I see no such function. The lack of this function is a problem for me as well in my existing apps. In order to deprecate nxutils, this functionality needs to be added to Path. Otherwise, nxutils *must* be reinstated before the next release. Michael has already agreed to make a nxutils compatibility layer that would have the same interface as the old nxutils. So we are talking about performance, not core functionality. We should remember that Michael did the lion's share of the work on porting mpl to python 3 ( https://github.com/matplotlib/matplotlib/pull/565/commits). He elected not to port all of the C++ if he could replace some of the functionality with the core. So those who rely on bare metal speed the you are getting in nxutils should step up to either : 1) help with the port of nxutils to python 3 2) help with exposing methods in _path.cpp that are almost as fast or faster 3) live with slower speeds in the compatibility layer he has agreed to write 4) ask (nicely) for someone to help you I prefer option 2 because this is fairly easy and avoids code redundancy. It would take just a few lines of extra code to do this with the python sequence protocol as inputs and python lists as return values. It would take a bit more to support numpy arrays as input and output, and we should get input from Michael about the desirability of making _path.cpp depend on numpy. I don't see the harm, but I'd like to verify. In my opinion, a slower implementation in a nxutils.py compatibility module is not a release stopper, even if it is undesirable.

They may be slightly slower because they have a few more checks and handle Bezier curves, but they are not significantly slower.

Now here is my question: Is it possible to grab the content of a figure and 'displace' it in a subplot of the same figure, to give room for a knew plot - even if the original content is complex (i.e. an image + a colorbar + an histogram, for example). I am not sure I'm clear here, so I can try to rephrase if needed. I am not sure if you are trying to move objects from one axes to another or merely reposition an existing axes to make room for a new one. Both are possible, but the latter is easy. Each axes has [left, bottom, width, height] rectangle in (0,1) figure coordinates that you can adjust at any time. See for example the subplots_adjust tool on the navigation toolbar next to the save icon http://matplotlib.sourceforge.net/api/axes_api.html#matplotlib.axes.Axes.set_position If you are working with subplots, also see the change_geometry method http://matplotlib.sourceforge.net/api/axes_api.html#matplotlib.axes.SubplotBase.change_geometry colorbars are a little tricky, because there you are needing to reposition *two* axes, one for the image, and one for the colorbar itself. You can do this manually, but you probably want to look at JJ's gridspec and axes_grid tools for laying out groups of axes: http://matplotlib.sourceforge.net/users/gridspec.html http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/index.html#toolkit-axesgrid-index JDH -- Virtualization Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

Thanks,
It's fairly easy to do if you want to set the tick locations and labels
youself (see http://matplotlib.sourceforge.net/users/artists.html near the
end for an overview of the mpl containers like Tick and the attributes they
contain).
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots(1)
ax.plot(np.random.randn(10,2)*10)
locs = np.arange(2, 10, 2)
labels = ['%d'%loc for loc in locs]
ticks, labels = plt.xticks(locs, labels)
i = 2
# tick1line and tick2line are matplotlib.lines.Line2D instances
ticks[i].tick1line.set_color('red')
ticks[i].tick2line.set_color('red')
labels[i].set_color('red')
plt.show()
If you want to add a tick using the existing mpl auto tick locating and
labeling infrastructure, it is also possible but you will need to subclass
the tick locator.

Since this entire story got started on this mailing list, I figured it would be appropriate to end it here. Love the alternate title. I'm sure we can all substitute dad|mom|wife|husband|significant_other in that one. About a week later, I got a personal email from the original poster informing me that my solution worked perfectly. He also noticed that I was working in a neighboring building on campus and wondered just how much longer my PhD was going to take and if I had any interest in going into the private sector. (The company happened to deal with atmospheric science and my PhD is in meteorology). I love that a tiny bit of altruism turned into a good job for you. Recently my wife, who is a criminal defense attorney, decided to transition from criminal law to family law, and took on a pro-bono case of a friend who was in a tough spot (he was accused of spousal battery by a mentally ill wife and they had several young kids in the middle). At a Halloween party, she met someone who worked at a family law firm and began telling him about her case, and that led to a job interview and soon she'll be having her third interview with the firm. I don't know how it will turn out, but I'm pretty sure that she wouldn't have gotten this opportunity had she not taken on this case pro-bono. I grew up pretty much accepting the US ethos that 'there is no such thing as free lunch and no one works for free. So it came as a great surprise to me, sometime in 1994-1995, when I posted a question on comp.lang.awk about a script I was developing mixing sed and awk which parsed BibTeX. Some kind soul responded withing 12 hours, you should really be using Perl for this, *and* wrote a non-trivial, several hundred line piece of Perl to solve my problem. I was dumbstruck that someone would stay up all night solving a problem for me, not looking for anything except perhaps for credit. What I learned next was that altruism is infectious. I began diving deeply into Perl, mastering it, and answering other people's questions on the Perl mailing list. At one point, I was one of the top ten posters on the Perl mailing list -- no mean feat at the time -- mainly obsessively answering people's questions. Of course when I discovered Python, I dropped Perl faster than a hot potato, but that spirit of contributing to and benefiting from a community of people motivated not by a payback but by contributing to and participating in something excellent persisted. That free help that guy gave me on comp.lang.awk probably caused me to spend 8,000 hours over the next decade helping other people. I guess there is no such thing as free lunch. It turned out that the company realized the value of having on-staff a SciPy Guru (I still consider myself a beginner). After the usual visits and interviews, I was offered a position. At multiple times throughout the process, it was obvious to me that while it was good that I was an atmospheric scientist, what was most valuable to them was my knowledge, insight and expertise with Python and its tools. The lesson I hope everyone here can take in is that there are many companies out there that are using open-source tools and libraries for their purposes. Learning and using these tools for your own purposes not only solves your immediate needs, but also sets you up for future opportunities. No doubt about this one. I have tried with mixed success on a number of occasions to hire people for a job in quantitative finance who possess skills in scientific python tools as well as statistics, and it is hard to find good matches. Whenever I meet other people like me who are trying to hire people, they all tell the same tale: it's hard to find talent. So if you have these skills and would like a job, contact me :-) I've been astounded by the degree of uptake of the scientific python toolset, and it is accelerating. As more and more people use these tools, more and more companies require them and most importantly, more and more talented developers put their energies into them. The amount of productivity being poured into not only the core tools but also pandas, scikits-learn, scikits-image, pystatsmodels and others is awesome, and is definitely taking the tool chain to the next level. Therefore, I would like to thank John Hunter for making matplotlib available for the community, and a hearty thanks to the rest of the community for their contributions to matplotlib. Without this, I doubt I would have found this job opportunity, nor have the value-added skills to have them consider hiring me. You're welcome, but I owe you a significant thanks as well. As my time for significant development has dwindled, the major contributions by you and the other developers has enabled the project to thrive. I hope that in your

Re: [Matplotlib-users] Unit testing code that generate matplotlib plots
On Wed, Nov 2, 2011 at 4:16 PM, Wes McKinney wesmck...@gmail.com wrote: Hi guys, Is there a common practice for unit testing code that creates matplotlib plots? I'm mainly just interested in code coverage versus correctness (making sure the code *works*) for now. I guess one way would be to disable the GUI backend so GUI elements don't get created (if the user is running the test suite from inside IPython in pylab mode, for example). Any tips or pointers to projects that do this would be very helpful. We have a unit testing framework for comparing images against baseline images using PIL to compare approximately close at the rendering level. The code lives in matplotlib.testing and is triggered by matplotlib.test. It might be heavyweight for what you want, so if all you want to do is insure it runs just create some figures using the agg backend and call savefig. You can use the pyplot.switch_backends to switch backends if you are concerned about a user calling it from ipython in an interactive session.

Since I want to use all CPU cores, I basically did for filename in files: execfile(filename) using a python script. However, this does not produce the same output as running each file separately (for instance axes, figure size are sometime wrong). I _think_ I narrowed it down to this: In all files I need to do matplotlib.rcParams(update). I guess that this influences the matplotlib rc parameters and thus somehow values from some figures are used for others. So, my question is, how can I do something like matplotlib.rcParams(update) so that it does not influence other scripts that are run in parallel using 'execfile'? Or, how do I set rc parameters for one specific script? BTW, I tried 'pp' and 'multiprocessing', same problem with both. The problem is that the rc params are module level in matplotlib so in a persistent process like ipython if one script modifies the rc params, subsequent files executed in the same process will be affected. You can restore the rc params to their default state by doing before each call to execfile import matplotlib matplotlib.rc_file_defaults() We face the same issue in the plot_directive which we use when building the matplotlib documentation. We define a function clear_state in https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/sphinxext/plot_directive.py#L484 which closes all open figures, restore the rc defaults, and the updates the defaults to an rc dictionary of the parameters we want for each run. -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

Re: [Matplotlib-users] canvas.draw() memory issue? (PyQt4)
Yes, it is possible. Everything that is possible in the pyplot
interface is available in the API (the pyplot interface is a thin
wrapper). Most plotting methods from pyplot like plot, semilogx,
imshow, scatter, etc, are axes instances
ax = fig.add_subplot(111)
ax.imshow(...)
and the title, xlabel, ylabel, etc, have associated set_* methods.
ax.set_xlabel('some labe').
All of the examples in the API directory follow this pattern

and you may want to take a look at the artist tutorial for a deeper
understanding

But at others have pointed out, your code is unnecessarily complex. Just do

matplotlib.use('agg')

and when you call savefig, you can pass ps, eps, pdf, png or svg and
the mpl code will choose the right backend, and never launch a GUI.

In functional programming terms, rec_summarize appears similar to “map”, rec_groupby appears similar to “reduce”. Now – what if I want to derive a calculation from multiple statistics in the original dataset – eg. create a new column on the array which is derived from 2 (or up to n) other fields in a custom function which I pass into the process? For example, conditional counts/summaries (count transactions and sum the sales on all orders that weighed 5K lbs). Is there a way to do this within numpy or mlab without going all the way out to python and creating a list comprehension? There are a couple of ways with the existing functions. One is to use a logical mask:: mask = r.weight5 rg = mlab.rec_groupby(r[mask], groupby, stats) You could also create a new categorical variable with one or more values and attach it to your record array and then use rec_groupby:: heavy = np.where(r.weight5, 1, 0) and add that to your record array r = mlab.rec_append_fields(r, ['heavy'], [heavy]) and then do a rec_group_by using 'heavy' as your group by attribute. Brian Schwartz has a preliminary implementation of rec_query which allows you to make a SQL query on a record array by converting it to a sqllite table, running the sql query, and returning the results as a new record array, which would solve your problem more cleanly and generically.

I happen to see the following problems with the plot() function and would appreciate any help to resolve these problems! 1. Using the default line style under plot() results in the function dropping data points from the plot. Plotting the same data with a ‘dot’ linestyle shows the missing data points. 2. Any large outliers in a data set are generally excluded from the resulting plot. The original plot generated using the default linestyle does not show the large outliers in the dataset. Further comparing against the second plot shows missing data points which were not connected by the default linestyle. Several missing data points are not necessarily large outliers. My initial guess for missing large outliers was that the function was aliasing down large values. Missing nominal data points makes me wonder if the plot function internally generates a “best-fit” or least squares plot of the data points? This inconsistent plot occurs only with large data sets. The two plots were generated with over 10 (hundred thousand) data points. Would be happy to send you the original data if that may help troubleshoot this problem. In all liklihood, you are using an older version of matplotlib which had a bug in the path.simplify logic that caused some points to be dropped.

Yes, this is the desired behavior. The interactive : True parameter

plt.figure()
plt.plot([1,2,3])

But nowadays drawing is done through draw_idle, so we don't trigger additional drawing even if interactive is True. In your example, if run as a script, there is no drawing until a call to show() is made, regardless of whether interactive is True or False. I see. I wasn't appreciating your point and had neglected to consider the idle drawing handling. Are we sure this will save us. Ie if we have a scirpt like # some plotting commands ... # some expensive non GUI computation ... # some update to plot above ... Would we not run the risk that the GUI is idle in the non GUI computation and therefore trigger a draw in it's thread, and then do redraws again after the update code? I did run some tests and confirmed what you said, that with the idle handling the repeat calls to pyplot commands did not generate extra calls (except in qtagg in which I suspect the idle handling has not been implemented. Are you proposing that we can get rid of the interactive setting entirely, always call draw on pyplot commands, and let the idle handler save us from doing repeated draws? -- Centralized Desktop Delivery: Dell and VMware Reference Architecture Simplifying enterprise desktop deployment and management using Dell EqualLogic storage and VMware View: A highly scalable, end-to-end client virtualization framework.

Re: [Matplotlib-users] Figure and Canvas
On Fri, Nov 12, 2010 at 4:20 AM, Olivier Verdier zelb...@gmail.com wrote: Hi, I would like to use matplotlib in a programmatic way. I thought about creating a Figure object (with no canvas), and plot in that Figure. Depending on what the user wants, I could then either plot on screen or save on file. The problem is that I don't know how to connect a Figure object to the FigureCanvas that the user chose in its preference file. In other words, I would like to do what the function figure() does, but for an existing Figure object. How could I do that? If you are using a GUI backend (eg GTKAgg, WXAgg, TkAgg, QtAgg) for your user interface and call fig.savefig with a hardcopy extension like PDF, PNG, SVG, EPS or PS, it will do the backend switching for you. If you'd like to see an example of how to do that for your own code if you need to, search for switch_backends in FigureCanvasBase: http://matplotlib.svn.sourceforge.net/viewvc/matplotlib/trunk/matplotlib/lib/matplotlib/backend_bases.py?revision=8791view=markup JDH -- Centralized Desktop Delivery: Dell and VMware Reference Architecture Simplifying enterprise desktop deployment and management using Dell EqualLogic storage and VMware View: A highly scalable, end-to-end client virtualization framework.

I see -- so it is raising the window even w/o show. This is a bug,

Re: [Matplotlib-users] problem with negative numbers on axes in EPS file when using in Latex file

I save the figure as EPS. When I look at the figure with preview on my Mac it looks fine. When I import the figure in my Latex document the negative values disappear. My solution has been to use eps2eps on the eps file created by mpl, and this solves the problem. So apparently there is something not quite standard on the EPS file created by MPL. Is this a bug? I am running version 0.99.3 (Enthought dis) on a Mac running Leopard. mpl by default uses the unicode minus symbol rather than the hyphen to indicate negative numbers. It looks like your system may not be recognizing it. The easiest solution is to set axes.unicode_minus : False in your matplotlib rc.

What have you tried -- if line is a Line3D object, the following should work:
line.set_markeredgecolor('None')
Note that 'None' is a string here, not the python object None. This
is because None in matplotlib properties means do the default, ie the
default value specified in matplotlibrc
