psd(),csd(), andcohere()will now automatically wrap negative frequency components to the beginning of the returned arrays. This is much more sensible behavior and makes them consistent withspecgram(). The previous behavior was more of an oversight than a design decision.Added new keyword parameters nonposx, nonposy to :class:`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 :func:`matplotlib.pyplot.fignum_exists` and :func:`matplotlib.pyplot.get_fignums`; they merely expose information that had been hidden in
matplotlib._pylab_helpers.Deprecated numerix package.
Added new :func:`matplotlib.image.imsave` and exposed it to the :mod:`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 :class:`matplotlib.legend.Legend` 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.
Removed the configobj and experimental traits rc support
Modified :func:`matplotlib.mlab.psd`, :func:`matplotlib.mlab.csd`, :func:`matplotlib.mlab.cohere`, and :func:`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 :class:`matplotlib.axes.Axes` methods and :mod:`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.
:meth:`matplotlib.axes.Axes.set_xlim`, :meth:`matplotlib.axes.Axes.set_ylim` now return a copy of the
viewlimarray to avoid modify-in-place surprises.matplotlib.afm.AFM.get_fullnameandmatplotlib.afm.AFM.get_familynameno 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 :func:`matplotlib.pyplot.spy`; default is 0, and the string value 'present' is used for sparse arrays only to show filled locations.
Added
angleskwarg to :func:`matplotlib.pyplot.quiver` for more flexible specification of the arrow angles.Deprecated (raise NotImplementedError) all the mlab2 functions from :mod:`matplotlib.mlab` out of concern that some of them were not clean room implementations.
Methods :meth:`matplotlib.collections.Collection.get_offsets` and :meth:`matplotlib.collections.Collection.set_offsets` added to :class:`~matplotlib.collections.Collection` base class.
matplotlib.figure.Figure.figurePatchrenamedmatplotlib.figure.Figure.patch;matplotlib.axes.Axes.axesPatchrenamedmatplotlib.axes.Axes.patch;matplotlib.axes.Axes.axesFramerenamedmatplotlib.axes.Axes.frame.matplotlib.axes.Axes.get_frame, which returnsmatplotlib.axes.Axes.patch, is deprecated.Changes in the :class:`matplotlib.contour.ContourLabeler` attributes (:func:`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_xyand.cl_cvalueshave been maintained for the moment (in addition to their renamed versions), but they are deprecated and will eventually be removed.Moved several functions in :mod:`matplotlib.mlab` and :mod:`matplotlib.cbook` into a separate module
matplotlib.numerical_methodsbecause they were unrelated to the initial purpose of mlab or cbook and appeared more coherent elsewhere.
