matplotlib-users Mailing List for matplotlib (Page 4)

This patch doesn't make a whole lot of sense to me.  get_name should 
work just fine if self._family is None, and indeed it does in my own 
testing:

```
from matplotlib import font_manager

f = font_manager.FontProperties(None)
print f._family
print f.get_family()
print f.get_name()
```

So I'd much prefer to get to the bottom of the root cause of this 
problem than patch it unnecessarily in this way.  Any idea what that is?

Can you please provide a completely standalone example?  The following 
code has undefined variables etc.

There is nothing available to push points -- matplotlib uses Numpy 
arrays internally for the data, and they can not be (efficiently) 
resized.  I would try implementing this before assuming it's too slow.

It works for me with OSX  Mountain Lion and mpl 1.2.1 compiled from 
source.  I don't think this is fundamentally a problem with 
cbook.report_memory.

Hi!

I have just run an old code that I believe was working before on OSX.
I am trying this with matplotlib 1.2.1 on an OSX EPD running Python 2.7.3


In [1]: from matplotlib.pylab import *

In [2]: import matplotlib.cbook as cbook

In [3]: data = ones((1500,1500,3))

In [4]: imshow(data)
Out[4]: <matplotlib.image.AxesImage at 0x109d343d0>

In [5]: ax = gca()

In [6]: print cbook.report_memory()
---------------------------------------------------------------------------
IOError                                   Traceback (most recent call last)
<ipython-input-6-88a73a5ab996> in <module>()
----> 1 print cbook.report_memory()

/Library/Frameworks/EPD64.framework/Versions/7.3/lib/python2.7/site-packages/matplotlib/cbook.py 
in report_memory(i)
   1210     elif sys.platform.startswith('darwin'):
   1211         a2 = Popen('ps -p %d -o rss,vsz' % pid, shell=True,
-> 1212                    stdout=PIPE).stdout.readlines()
   1213         mem = int(a2[1].split()[0])
   1214     elif sys.platform.startswith('win'):

IOError: [Errno 4] Interrupted system call

First I thought, maybe this doesn't run in IPython for a reason, but 
trying it as a script also fails:

(general_dev+)[maye@lunatic ~/Dropbox/src/pymars]$ python imshow_test.py
Traceback (most recent call last):
  File "imshow_test.py", line 7, in <module>
    print cbook.report_memory()
  File 
"/Library/Frameworks/EPD64.framework/Versions/7.3/lib/python2.7/site-packages/matplotlib/cbook.py", 
line 1212, in report_memory
    stdout=PIPE).stdout.readlines()
IOError: [Errno 4] Interrupted system call


Is this cbook recipe maybe broken?

Best,
Michael

Hi,

Is there a way to make the below as a hovemuler diagram which I tired but could not succeed  

import pandas as pd
 
dates = pd.date_range('20130101',periods=30)
df=pd.DataFrame(np.random.randn(30,5),index=dates)

The installation process is only going to get easier over time, for instance last week we added a PPA so that with the necessary repos added you would be able to "apt-get install python-iris" on an Ubuntu machine - for other installation guides there is a repository of recipes ( https://github.com/SciTools/installation-recipes ).

From memory you might also need to tell matplotlib that the y coordinate is date/time (I think that is a mpl bug that ajdawson has recently addressed). Obviously, basemap is not needed as you are not drawing a longitude/latitude plot but a longitude/time or latitude/time one.

                   Got it, you meant the data should not have date and longitude against each grid point instead should have only 2 vectors rather than grid.
with best regards,
Sudheer

I meant the coordinates, so one representing latitude or longitude and one
representing time (filled with datetime objects), should be 1d. This only
applies if your coordinate actually contains datetime objects, if not then
coordinates can be 2d as the documentation says.

Sudheer,

Although the documentation is not consistent with the following (as of v1.0.1), the X and Y arguments to contourf can be 1D arrays.  Consider:
>>> from pylab import *
>>> x=range(100)
>>> y=range(20)
>>> xx,yy=meshgrid(x,y)
>>> z=xx**2+yy**2
>>> contourf(x,y,z)
<matplotlib.contour.QuadContourSet instance at 0x114e5fa28>

                       Which repository I need to add to source list which allow me to install iris with apt-get install python-iris. I do not have it in my default lists.
with best regards,
Sudheer

From memory you might also need to tell matplotlib that the y coordinate is date/time (I think that is a mpl bug that ajdawson has recently addressed). Obviously, basemap is not needed as you are not drawing a longitude/latitude plot but a longitude/time or latitude/time one.

Also tried building from source with python2.7 - same problem:

I deleted the old build/source directory, re-extracted the source from the
tar file and tried...
[lap3:~/matplotlib-1.2.1] pflm% sudo python2.7 setup.py install

Build runs ok except for some warnings like ...

Skip,

I am not at all familiar with dates in matplotlib, but what does plt.xlim() yield?  Or are the limits not updated before calling the tick formatter?

Bingo!  I changed "plt" to "pylab" and now I have access to the x
range of the current viewport.

Thanks,

Skip

Let me return to my FuncFormatter usage.  As I indicated in an earlier
post, I made a single format decision based on the x range of the
entire data set.  The decision code was straightforward:

    x_delta = x_range[1] - x_range[0]
    if x_delta > int(1.5 * 365) * ONE_DAY:
        xfmt = "%Y-%m-%d"
    elif x_delta > 2 * ONE_DAY:
        xfmt = "%m/%d\n%H:%M"
    elif x_delta < 2 * ONE_HOUR:
        xfmt = "%H:%M:%S"
    else:
        xfmt = "%H:%M"

How do I compute x_delta as it relates to the currently visible
window?  In the above code, x_range represents the x range of my
entire data set.

Thx,

My memory failed me.  I not only proposed, but submitted the necessary
patches which were accepted.  However, this only works for datetime
objects:

>>> import datetime
>>> datetime.datetime.now().strftime("%H:%M:%S.%f")
'08:58:57.854562'

It's not supported by time.strftime:

>>> import time
>>> time.time()
1373637581.478104
>>> time.strftime("%H:%M:%S.%f", time.localtime())
'09:00:10.%f'

which I suspect is what matplotlib uses if it converts datetime
objects to floats internally.

Did that.  Works just as before with my custom FuncFormatter, and with
my explicit AutoDateFormatter.  Hmmm...  Looking at the default scaled
dictionary, I suspect I failed to understand exactly what its scale
is.  Perhaps all the examples I've used so far have generally been
less than 24 hours in duration. Let me play with that, but ask a
corollary question:  Is there some way to get the x axis to display
fractions of a second?  There is no strftime format character
corresponding to that.  (I proposed one on python-dev several years
ago, but I don't think it was ever adopted.)

Thx,

Skip

> Are you definately passing through datetime objects, or are you passing
> through the datetime "ordinals" / Julian time?

Definitely datetime objects:

    if xtime:
        min_x = datetime.datetime(9999, 12, 31, 23, 59, 59)
        max_x = datetime.datetime(1970, 1, 1, 0, 0, 0)
        def parse_x(x):
            try:
                return dateutil.parser.parse(x)
            except ValueError:
                print >> sys.stderr, "Can't parse", repr(x), "as a timestamp."
                raise
        ...

You're suggesting that I shouldn't have to do anything with formatters
and locators if my X values are datetime objects?  Maybe I should
simply scrub any locator/formatter initialization altogether.  When I
first started this little tool I used a FuncFormatter which (unknown
to me) performed about like the AutoDateFormatter without the "Auto"
part.  It simply selected the X axis format based on the range of the
data.

Could you please point me to this PPA?
Where can I find the link?

As long as you use contour or contourf and your coordinates are 1d you
should be able to do this no problem, just like Phil said. However, there
is a bug that will prevent you from using pcolormesh or pcolor
unfortunately.

The balance of time to install vs time to re-implement a feature is only
something you can decide, but i suspect it is worth your while getting iris
installed (I would say that as an iris developer though). The installation
process is only going to get easier over time, for instance last week we
added a PPA so that with the necessary repos added you would be able to
"apt-get install python-iris" on an Ubuntu machine - for other installation
guides there is a repository of recipes (
https://github.com/SciTools/installation-recipes ).

As for achieving this without iris, it is perfectly feasible. You just need
to contourf your data with the longitude as your x coordinate and the date
times as your y coordinate. From memory you might also need to tell
matplotlib that the y coordinate is date/time (I think that is a mpl bug
that ajdawson has recently addressed). Obviously, basemap is not needed as
you are not drawing a longitude/latitude plot but a longitude/time or
latitude/time one.

HTH,

This surprises me as the AutoDateFormatter automatically kicks in once you
pass through some datetime objects, and the AutoDateFormatter & Locator do
the right thing when zooming (the format changes depending on the temporal
resolution). For example, the following code behaves nicely when I zoom in
to a small segment of the line:

import datetime as dt
import numpy as np
import matplotlib.pyplot as plt


d1 = dt.datetime(1990, 1, 1)

n = 365
x = np.array([d1 + dt.timedelta(days=i) for i in range(n)], dtype=object)

y = np.sin(np.linspace(0, np.pi * 2, n))

plt.plot(x, y)

plt.show()



Are you definately passing through datetime objects, or are you passing
through the datetime "ordinals" / Julian time?

Cheers,

Phil

Thank you Signell,
                       I was looking for better looking labels as well as a solution with in matplotlib without needing to install additional packages. I had some trouble with some libraries while trying to install iris. I was wondering if it is possible with in matplotlib with out additional installations using the features of basemap package.
with best regards,
Sudheer
