demo_ribbon_box.py added. - JJL

2009-08-07 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)

becomes:

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)

becomes:

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)

becomes:

draw_image(self, gc, x, y, im)

in OffsetBox-JJL

2009-05-13 When the x-coordinate of a line is monotonically

increasing, it is now automatically clipped at

the stage of generating the transformed path in

the draw method; this greatly speeds up zooming and

panning when one is looking at a short segment of

a long time series, for example. - EF

2009-05-11 aspect=1 in log-log plot gives square decades. -JJL

2009-05-08 clabel takes new kwarg, rightside_up; if False, labels

2008-12-16 Added markevery property to Line2D to support subsampling

of markers - JDH

2008-12-15 Removed mpl_data symlink in docs. On platforms that do not

support symlinks, these become copies, and the font files

are large, so the distro becomes unneccessarily bloaded.

Keeping the mpl_examples dir because relative links are

harder for the plot directive and the *.py files are not so

large. - JDH

2008-12-15 Fix \$ in non-math text with usetex off. Document

differences between usetex on/off - MGD

2008-12-15 Fix anti-aliasing when auto-snapping - MGD

2008-12-15 Fix grid lines not moving correctly during pan and zoom - MGD

to the axes hist() method. Docs taken from numpy - MM

2008-12-12 Fixed warning in hist() with numpy 1.2 - MM

2008-12-12 Removed external packages: configobj and enthought.traits

which are only required by the experimental traited config

independently, see:

http://code.enthought.com/projects/traits

and:

http://www.voidspace.org.uk/python/configobj.html

2008-12-08 Added mdehoon's native macosx backend from sf patch 2179017 - JDH

2008-12-08 Removed the prints in the set_*style commands. Return the

list of pprinted strings instead - JDH

2008-12-08 Some of the changes Michael made to improve the output of

the property tables in the rest docs broke of made

difficult to use some of the interactive doc helpers, eg

setp and getp. Having all the rest markup in the ipython

shell also confused the docstrings. I added a new rc param

docstring.harcopy, to format the docstrings differently for

hardcopy and other use. Ther ArtistInspector could use a

little refactoring now since there is duplication of effort

between the rest out put and the non-rest output - JDH

2008-12-08 Updated spectral methods (psd, csd, etc.) to scale one-sided

densities by a factor of 2 and, optionally, scale all densities

by the sampling frequency. This gives better MatLab

compatibility. -RM

2008-12-07 drop the deprecated "new" keyword of np.histogram() for

numpy 1.2 or later. -JJL

set too short when numpoints=1 -JJL

2008-12-04 Added support for data with units (e.g. dates) to

Axes.fill_between. -RM

2008-12-04 Added fancybox keyword to legend. Also applied some changes

for better look, including baseline adjustment of the

multiline texts so that it is center aligned. -JJL

2008-12-02 The transmuter classes in the patches.py are reorganized as

subclasses of the Style classes. A few more box and arrow

styles are added. -JJL

2008-12-02 Fixed a bug in the new legend class that didn't allowed

a tuple of coordinate vlaues as loc. -JJL

2008-12-02 Improve checks for external dependencies, using subprocess

checking) - DSD

2008-11-30 Reimplementaion of the legend which supports baseline alignement,

multi-column, and expand mode. - JJL

2008-12-01 Fixed histogram autoscaling bug when bins or range are given

and Axes/pyplot method fill_between. See

examples/pylab/fill_between.py - JDH

2008-11-12 Add x_isdata and y_isdata attributes to Artist instances,

and use them to determine whether either or both

coordinates are used when updating dataLim. This is

used to fix autoscaling problems that had been triggered

by axhline, axhspan, axvline, axvspan. - EF

2008-11-11 Update the psd(), csd(), cohere(), and specgram() methods

of Axes and the csd() cohere(), and specgram() functions

in mlab to be in sync with the changes to psd().

In fact, under the hood, these all call the same core

to do computations. - RM

2008-11-11 Add 'pad_to' and 'sides' parameters to mlab.psd() to

allow controlling of zero padding and returning of

negative frequency components, respecitively. These are

added in a way that does not change the API. - RM

2008-11-10 Fix handling of c kwarg by scatter; generalize

is_string_like to accept numpy and numpy.ma string

array scalars. - RM and EF

2008-11-09 Fix a possible EINTR problem in dviread, which might help
