Changes beyond 0.99.x
=====================
* The default behavior of :meth:`matplotlib.axes.Axes.set_xlim`,
:meth:`matplotlib.axes.Axes.set_ylim`, and
:meth:`matplotlib.axes.Axes.axis`, and their corresponding
pyplot functions, has been changed: when view limits are
set explicitly with one of these methods, autoscaling is turned
off for the matching axis. A new *auto* kwarg is available to
control this behavior. The limit kwargs have been renamed to
*left* and *right* instead of *xmin* and *xmax*, and *bottom*
and *top* instead of *ymin* and *ymax*. The old names may still
be used, however.
* There are five new Axes methods with corresponding pyplot
functions to facilitate autoscaling, tick location, and tick
label formatting, and the general appearance of ticks and
tick labels:
+ :meth:`matplotlib.axes.Axes.autoscale` turns autoscaling
on or off, and applies it.
+ :meth:`matplotlib.axes.Axes.margins` sets margins used to
autoscale the ``matplotlib.axes.Axes.viewLim`` based on
the ``matplotlib.axes.Axes.dataLim``.
+ :meth:`matplotlib.axes.Axes.locator_params` allows one to
adjust axes locator parameters such as *nbins*.
+ :meth:`matplotlib.axes.Axes.ticklabel_format` is a convenience
method for controlling the :class:`matplotlib.ticker.ScalarFormatter`
that is used by default with linear axes.
+ :meth:`matplotlib.axes.Axes.tick_params` controls direction, size,
visibility, and color of ticks and their labels.
* The :meth:`matplotlib.axes.Axes.bar` method accepts a *error_kw*
kwarg; it is a dictionary of kwargs to be passed to the
errorbar function.
* The :meth:`matplotlib.axes.Axes.hist` *color* kwarg now accepts
a sequence of color specs to match a sequence of datasets.
* The :class:`~matplotlib.collections.EllipseCollection` has been
changed in two ways:
+ There is a new *units* option, 'xy', that scales the ellipse with
the data units. This matches the :class:'~matplotlib.patches.Ellipse`
scaling.
+ The *height* and *width* kwargs have been changed to specify
the height and width, again for consistency with
:class:`~matplotlib.patches.Ellipse`, and to better match
their names; previously they specified the half-height and
half-width.
* There is a new rc parameter ``axes.color_cycle``, and the color
cycle is now independent of the rc parameter ``lines.color``.
``matplotlib.Axes.set_default_color_cycle`` is deprecated.
* You can now print several figures to one pdf file and modify the
document information dictionary of a pdf file. See the docstrings
of the class :class:`matplotlib.backends.backend_pdf.PdfPages` for
more information.
* Removed configobj_ and `enthought.traits`_ packages, which are only
required by the experimental traited config and are somewhat out of
date. If needed, install them independently.

.. _`enthought.traits`: http://code.enthought.com/pages/traits.html
* The new rc parameter ``savefig.extension`` sets the filename extension
that is used by :meth:`matplotlib.figure.Figure.savefig` if its *fname*
argument lacks an extension.
* In an effort to simplify the backend API, all clipping rectangles
and paths are now passed in using GraphicsContext objects, even
on collections and images. Therefore::
draw_path_collection(self, master_transform, cliprect, clippath,
clippath_trans, paths, all_transforms, offsets,
offsetTrans, facecolors, edgecolors, linewidths,
linestyles, antialiaseds, urls)
# is now
draw_path_collection(self, gc, master_transform, paths, all_transforms,
offsets, offsetTrans, facecolors, edgecolors,
linewidths, linestyles, antialiaseds, urls)
draw_quad_mesh(self, master_transform, cliprect, clippath,
clippath_trans, meshWidth, meshHeight, coordinates,
offsets, offsetTrans, facecolors, antialiased,
showedges)
# is now
draw_quad_mesh(self, gc, master_transform, meshWidth, meshHeight,
coordinates, offsets, offsetTrans, facecolors,
antialiased, showedges)
draw_image(self, x, y, im, bbox, clippath=None, clippath_trans=None)
# is now
draw_image(self, gc, x, y, im)
* There are four new Axes methods with corresponding pyplot
functions that deal with unstructured triangular grids:
+ :meth:`matplotlib.axes.Axes.tricontour` draws contour lines
on a triangular grid.
+ :meth:`matplotlib.axes.Axes.tricontourf` draws filled contours
on a triangular grid.
+ :meth:`matplotlib.axes.Axes.tripcolor` draws a pseudocolor
plot on a triangular grid.
+ :meth:`matplotlib.axes.Axes.triplot` draws a triangular grid
as lines and/or markers.
