Changes for 0.98.x#
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
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()
andmatplotlib.pyplot.get_fignums()
; they merely expose information that had been hidden inmatplotlib._pylab_helpers
.Deprecated numerix package.
Added new
matplotlib.image.imsave()
and exposed it to thematplotlib.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.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.Deprecated

Modified
matplotlib.mlab.psd()
,matplotlib.mlab.csd()
,matplotlib.mlab.cohere()
, andmatplotlib.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 correspondingmatplotlib.axes.Axes
methods andmatplotlib.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 theviewlim
array to avoid modify-in-place surprises.matplotlib.afm.AFM.get_fullname
andmatplotlib.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 tomatplotlib.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()
andmatplotlib.collections.Collection.set_offsets()
added toCollection
base class.matplotlib.figure.Figure.figurePatch
renamedmatplotlib.figure.Figure.patch
;matplotlib.axes.Axes.axesPatch
renamedmatplotlib.axes.Axes.patch
;matplotlib.axes.Axes.axesFrame
renamedmatplotlib.axes.Axes.frame
.matplotlib.axes.Axes.get_frame
, which returnsmatplotlib.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
andmatplotlib.cbook
into a separate modulematplotlib.numerical_methods
because they were unrelated to the initial purpose of mlab or cbook and appeared more coherent elsewhere.
