psd(), csd(), and cohere() will now automatically wrap negative frequency components to the beginning of the returned arrays. This is much more sensible behavior and makes them consistent with specgram(). The previous behavior was more of an oversight than a design decision.
Added new keyword parameters nonposx, nonposy to
matplotlib.axes.Axes
methods that set log scale
parameters. The default is still to mask out non-positive
values, but the kwargs accept 'clip', which causes non-positive
values to be replaced with a very small positive value.
Added new matplotlib.pyplot.fignum_exists()
and
matplotlib.pyplot.get_fignums()
; they merely expose
information that had been hidden in matplotlib._pylab_helpers
.
Deprecated numerix package.
Added new matplotlib.image.imsave()
and exposed it to the
matplotlib.pyplot
interface.
Remove support for pyExcelerator in exceltools -- use xlwt instead
Changed the defaults of acorr and xcorr to use usevlines=True, maxlags=10 and normed=True since these are the best defaults
Following keyword parameters for matplotlib.label.Label
are now
deprecated and new set of parameters are introduced. The new parameters
are given as a fraction of the font-size. Also, scatteryoffsets,
fancybox and columnspacing are added as keyword parameters.
Deprecated New pad borderpad labelsep labelspacing handlelen handlelength handlestextsep handletextpad axespad borderaxespad
Removed the configobj and experimental traits rc support
Modified matplotlib.mlab.psd()
, matplotlib.mlab.csd()
,
matplotlib.mlab.cohere()
, and matplotlib.mlab.specgram()
to scale one-sided densities by a factor of 2. Also, optionally
scale the densities by the sampling frequency, which gives true values
of densities that can be integrated by the returned frequency values.
This also gives better MATLAB compatibility. The corresponding
matplotlib.axes.Axes
methods and matplotlib.pyplot
functions were updated as well.
Font lookup now uses a nearest-neighbor approach rather than an exact match. Some fonts may be different in plots, but should be closer to what was requested.
matplotlib.axes.Axes.set_xlim()
,
matplotlib.axes.Axes.set_ylim()
now return a copy of the
viewlim
array to avoid modify-in-place surprises.
matplotlib.afm.AFM.get_fullname()
and
matplotlib.afm.AFM.get_familyname()
no longer raise an
exception if the AFM file does not specify these optional
attributes, but returns a guess based on the required FontName
attribute.
Changed precision kwarg in matplotlib.pyplot.spy()
; default is
0, and the string value 'present' is used for sparse arrays only to
show filled locations.
Added angles
kwarg to matplotlib.pyplot.quiver()
for more
flexible specification of the arrow angles.
Deprecated (raise NotImplementedError) all the mlab2 functions from
matplotlib.mlab
out of concern that some of them were not
clean room implementations.
Methods matplotlib.collections.Collection.get_offsets()
and
matplotlib.collections.Collection.set_offsets()
added to
Collection
base class.
matplotlib.figure.Figure.figurePatch
renamed
matplotlib.figure.Figure.patch
;
matplotlib.axes.Axes.axesPatch
renamed
matplotlib.axes.Axes.patch
;
matplotlib.axes.Axes.axesFrame
renamed
matplotlib.axes.Axes.frame
.
matplotlib.axes.Axes.get_frame()
, which returns
matplotlib.axes.Axes.patch
, is deprecated.
Changes in the matplotlib.contour.ContourLabeler
attributes
(matplotlib.pyplot.clabel()
function) so that they all have a
form like .labelAttribute
. The three attributes that are most
likely to be used by end users, .cl
, .cl_xy
and
.cl_cvalues
have been maintained for the moment (in addition to
their renamed versions), but they are deprecated and will eventually
be removed.
Moved several functions in matplotlib.mlab
and
matplotlib.cbook
into a separate module
matplotlib.numerical_methods
because they were unrelated to
the initial purpose of mlab or cbook and appeared more coherent
elsewhere.
