Changes for 0.98.x
==================
+* 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 :mod:`matplotlib._pylab_helpers`.

Natgrid
========
-
+
mpl_toolkits.natgrid is an interface to natgrid C library for gridding
irregularly spaced data. This requires a separate installation of the
natgrid toolkit from the sourceforge `download

+mplot3d
+===========
+
+mpl_toolkits.mplot3d provides some basic 3D plotting (scatter, surf,
+line, mesh) tools. Not the fastest or feature complete 3D library out
+there, but ships with matplotlib and thus may be a lighter weight
+solution for some use cases.

+AxesDivider
+===========
+
+The axes_divider module provide helper classes to adjust the axes
+positions of set of images in the drawing time.
+
+* *Size* This provides a classese of units that the size of each axes
+ will be determined. For example, you can specify a fixed size
+
+* *Divider* this is the class that is used calculates the axes
+ position. It divides the given renctangular area into several
+ areas. You intialize the divider by setting the horizontal and
+ vertical list of sizes that the division will be based on. You then
+ use the new_locator method, whose return value is a callable object
+ that can be used to set the axes_locator of the axes.
+
+
+You first initialize the divider by specifying its grids, i.e., horiz and vert.
+
+for example,::
+
+ rect = [0.2, 0.2, 0.6, 0.6]
+ horiz=[h0, h1, h2, h3]
+ vert=[v0, v1, v2]
+ divider = Divider(fig, rect, horiz, vert)
+
+where, rect is a bounds of the box that will be divided and h0,..h3,
+v0,..v2 need to be an callable object that returns a tuple of two
+floats. The first float is the relative size, and the second float is
+the absolute size. Use of the subclasses contained in the Size class
+is recommanded. Lets' consider a following grid.
+
++-----+-----+-----+-----+
+| v0 | | | |
++-----+-----+-----+-----+
+| v1 | | | |
++-----+-----+-----+-----+
+|h0,v2| h1 | h2 | h3 |
++-----+-----+-----+-----+
+
+
+* h0 => 2, 0
+* h1 => 0, 2
+* h2 => 0, 3
+
+The height of the bottom row is always 2 (axes_divider internally
+assumes that the unit is inch). The first and the second rows with
+height ration of 2:3. For example, if the total height of the grid 6,
+the the first and second row will each occupy 2/(2+3) and 3/(2+3) of
+(6-1) inches. The widths of columns (horiz) will be similarly
+determined. When aspect ratio is set, the total height (or width) will
+be adjusted accordingly.
+
+
+The Size class is a container class that contains several sub-class
+that can be used to set the horiz and vert. For example, for the
+vertical configuration above will be::
+
+ from Size import Fixed, Scaled
+ vert = [Fixed(2), Scaled(2), Scaled(3)]
+
+After you set up the divider object, you
+Then you create a locator instance which will be given to the axes.::
+
+ locator = divider.new_locator(nx=0, ny=1)
+ ax.set_axes_locator(locator)
+
+The return value of the new_locator method is a instance of the
+AxesLocator class. It is a callable object that will return the
+location and size of the cell at the first column and the second row.
+You may create a locator that spans over multiple cells.::
+
+ locator = divider.new_locator(nx=0, nx=2, ny=1)
+
+The above locator, when called, will return the position and size of
+the cells spanning the first and second column and the first row. You
+may consider it as [0:2, 1].
+
+See the example,
+
+.. plot:: mpl_toolkits/axes_grid/figures/simple_axes_divider2.py
+ :include-source:
+
+You can adjust the size of the each axes accroding to their x or y
+data limits (AxesX and AxesY), similar to the axes aspect parameter.

+=================
+AxesGrid Overview
+=================
+
+The matplotlib AxesGrid toolkit is a collection of helper classes,
+mainly to ease displaying (multiple) images in matplotlib.
+
+.. contents::
+ :depth: 1
+ :local:
+
+`AxesGrid`_, `RGB Axes`_ and `AxesDivider`_ are helper classes that
+deals with adjusting the location of (multiple) Axes, mainly for
+displaying images. It provides a framework to adjust the position of
+multiple axes at the drawing time. `ParasiteAxes`_ provides twinx(or
+twiny)-like features so that you can plot different data (e.g.,
+different y-scale) in a same Axes. `AxisLine`_ is a custom Axes
+class. Unlike default Axes in matpotlib, each axis (left, right, top
+and bottom) is associated with a separate artist (which is resposible
+to draw axis-line, ticks, ticklabels, label). `AnchoredArtists`_
+includes custom artists which are placed at some anchored position,
+like the legend.
+
+
+
+
+AxesGrid
+========
+
+
+A class that creates a grid of Axes. In matplotlib, the axes location
+(and size) is specified in the normalized figure coordinates. This may
+not be ideal for images that needs to be displayed with a given aspect
+ratio. For example, displaying images of a same size with some fixed
+padding between them cannot be easily done in matplotlib. AxesGrid is
+used in such case.
+
+.. plot:: mpl_toolkits/axes_grid/figures/simple_axesgrid.py
+ :include-source:
+
+* The postion of each axes is determined at the drawing time (see
+ `AxesDivider`_), so that the size of the entire grid fits in the
+ given rectangle (like the aspec of axes). Note that in this example,
+ the paddings between axes are fixed even if you changes the figure
+ size.
+
+* axes in the same column has a same axes width (in figure
+ coordinate), and similarly, axes in the same row has a same
+ height. The widths (height) of the axes in the same row (column) are
+ scaled according to their view limits (xlim or ylim).
+
+ .. plot:: mpl_toolkits/axes_grid/figures/simple_axesgrid2.py
+ :include-source:
+
+* xaxis are shared among axes in a same column. Similarly, yaxis are
+ shared among axes in a same row. Therefore, changing axis properties
+ (view limits, tick location, etc. either by plot commands or using
+ your mouse in interactive backends) of one axes will affect all
+ other shared axes.
+
+
+
+When initialized, AxesGrid creates given number (*ngrids* or *ncols* *
+*nrows* if *ngrids* is None) of Axes instances. A sequence-like
+interface is provided to access the individual Axes instances (e.g.,
+grid[0] is the first Axes in the grid. See below for the order of
+axes).
+
+
+
+AxesGrid takes following arguments,
+
+
+ ============= ======== ================================================
+ Name Default Description
+ ============= ======== ================================================
+ fig
+ rect
+ nrows_ncols number of rows and cols. e.g. (2,2)
+ ngrids None number of grids. nrows x ncols if None
+ direction "row" increasing direction of axes number. [row|column]
+ axes_pad 0.02 pad between axes in inches
+ add_all True Add axes to figures if True
+ share_all False xaxis & yaxis of all axes are shared if True
+ aspect True aspect of axes
+ label_mode "L" location of tick labels thaw will be displayed.
+ "1" (only the lower left axes),
+ "L" (left most and bottom most axes),
+ or "all".
+ cbar_mode None [None|single|each]
+ cbar_location "right" [right|top]
+ cbar_pad None pad between image axes and colorbar axes
+ cbar_size "5%" size of the colorbar
+ axes_class None
+ ============= ======== ================================================
+
+ *rect*
+ specifies the location of the grid. You can either specify
+ coordinates of the rectangle to be used (e.g., (0.1, 0.1, 0.8, 0.8)
+ as in the Axes), or the subplot-like position (e.g., "121").
+
+ *direction*
+ means the increasing direction of the axes number.
+
+ *aspect*
+ By default (False), widths and heigths of axes in the grid are
+ scaled independently. If True, they are scaled according to their
+ data limits (similar to aspect parameter in mpl).
+
+ *share_all*
+ if True, xaxis and yaxis of all axes are shared.
+
+ *direction*
+ direction of increasing axes number. For "row",
+
+ +---------+---------+
+ | grid[0] | grid[1] |
+ +---------+---------+
+ | grid[2] | grid[3] |
+ +---------+---------+
+
+ For "column",
+
+ +---------+---------+
+ | grid[0] | grid[2] |
+ +---------+---------+
+ | grid[1] | grid[3] |
+ +---------+---------+
+
+You can also create a colorbar (or colobars). You can have colorbar
+for each axes (cbar_mode="each"), or you can have a single colorbar
+for the grid (cbar_mode="single"). The colorbar can be placed on your
+right, or top. The axes for each colorbar is stored as a *cbar_axes*
+attribute.
+
+
+
+The examples below show what you can do with AxesGrid.
+
+.. plot:: mpl_toolkits/axes_grid/figures/demo_axes_grid.py
+
+
+RGB Axes
+========
+
+RGBAxes is a helper clase to conveniently show RGB composite
+images. Like AxesGrid, the location of axes are adjusted so that the
+area occupied by them fits in a given rectangle. Also, the xaxis and
+yaxis of each axes are shared. ::
+
+ from mpl_toolkits.axes_grid.axes_rgb import RGBAxes
+
+ fig = plt.figure(1)
+ ax = RGBAxes(fig, [0.1, 0.1, 0.8, 0.8])
+
+ r, g, b = get_rgb() # r,g,b are 2-d images
+ ax.imshow_rgb(r, g, b,
+ origin="lower", interpolation="nearest")
+
+
+.. plot:: mpl_toolkits/axes_grid/figures/simple_rgb.py
+
+
+
+AxesDivider
+===========
+
+Behind the scene, the AxesGrid class and the RGBAxes class utilize the
+AxesDivider class, whose role is to calculate the location of the axes
+at drawing time. While a more about the AxesDivider is (will be)
+explained in (yet to be written) AxesDividerGuide, direct use of the
+AxesDivider class will not be necessary for most users. The
+axes_divider module provides a helper function make_axes_locatable,
+which can be useful. It takes a exisitng axes instance and create a
+divider for it. ::
+
+ ax = subplot(1,1,1)
+ divider = make_axes_locatable(ax)
+
+
+
+
+*make_axes_locatable* returns an isntance of the AxesLocator class,
+derived from the Locator. It has *new_vertical*, and *new_horizontal*
+methods. The *new_vertical* (*new_horizontal*) creates a new axes on
+the upper (right) side of the original axes.
+
+
+scatter_hist.py with AxesDivider
+--------------------------------
+
+The "scatter_hist.py" example in mpl can be rewritten using
+*make_axes_locatable*. ::
+
+ from mpl_toolkits.axes_grid import make_axes_locatable
+
+ axScatter = subplot(111)
+ divider = make_axes_locatable(axScatter)
+
+ # create new axes on the right and on the top of the current axes
+ # The first argument of the new_vertical(new_horizontal) method is
+ # the height (width) of the axes to be created in inches.
+ axHistx = divider.new_vertical(1.2, pad=0.1, sharex=axScatter)
+ axHisty = divider.new_horizontal(1.2, pad=0.1, sharey=axScatter)
+
+ fig.add_axes(axHistx)
+ fig.add_axes(axHisty)
+
+
+ # the scatter plot:
+ axScatter.scatter(x, y)
+ axScatter.set_aspect(1.)
+
+ # histograms
+ bins = np.arange(-lim, lim + binwidth, binwidth)
+ axHistx.hist(x, bins=bins)
+ axHisty.hist(y, bins=bins, orientation='horizontal')
+
+See the full source code below.
+
+
+.. plot:: mpl_toolkits/axes_grid/figures/scatter_hist.py
+
+
+The scatter_hist using the AxesDivider has some advantage over the
+original scatter_hist.py in mpl. For example, you can set the aspect
+ratio of the scatter plot, even with the x-axis or y-axis is shared
+accordingly.
+
+
+ParasiteAxes
+============
+
+The ParasiteAxes is a axes whose location is identical to its host
+axes. The location is adjusted in the drawing time, thus it works even
+if the host change its location (e.g., images). It provides *twinx*,
+*twiny* (similar to twinx and twiny in the matplotlib). Also it
+provides *twin*, which takes an arbitraty tranfromation that maps
+between the data coordinates of the host and the parasite axes.
+Artists in each axes are mergred and drawn acrroding to their zorder.
+It also modifies some behavior of the axes. For example, color cycle
+for plot lines are shared between host and parasites. Also, the legend
+command in host, creates a legend that includes lines in the parasite
+axes.
+
+Example 1. twinx
+----------------
+
+.. plot:: mpl_toolkits/axes_grid/figures/parasite_simple.py
+ :include-source:
+
+Example 2. twin
+---------------
+
+A more sophiscated example using twin. Note that if you change the
+x-limit in the host axes, the x-limit of the parasite axes will change
+accordingly.
+
+
+.. plot:: mpl_toolkits/axes_grid/figures/parasite_simple2.py
+
+
+
+AxisLine
+========
+
+AxisLine is a custom (and very experimenta) Axes class, where each
+axis (left, right, top and bottom) have a separate artist associated
+(which is resposible to draw axis-line, ticks, ticklabels, label).
+Also, you can create your own axis, which can pass through a fixed
+position in the axes coordinate, or a fixed position in the data
+coordinate (i.e., the axis floats around when viewlimit changes).
+
+Most of the class in this toolkit is based on this class. And it has
+not been tested extensibly. You may go back to the original mpl
+behanvior, by ::
+
+ ax.toggle_axisline(False)
+
+The axes class, by default, provides 4 artists which are responsible
+to draw axis in "left","right","bottom" and "top". They are accessed
+as ax.axis["left"], ax.axis["right"], and so on, i.e., ax.axis is a
+dictionary that contains artists (note that ax.axis is still a
+callable methods and it behaves as an original Axes.axis method in
+mpl).
+
+For example, you can hide right, and top axis by ::
+
+ ax.axis["right"].set_visible(False)
+ ax.axis["top"].set_visible(False)
+
+
+.. plot:: mpl_toolkits/axes_grid/figures/simple_axisline3.py
+
+
+SubplotZero gives you two more additional (floating?) axis of x=0 and
+y=0 (in data coordinate)
+
+.. plot:: mpl_toolkits/axes_grid/figures/simple_axisline2.py
+ :include-source:
+
+
+Axisline with ParasiteAxes
+--------------------------
+
+Most of axes class in the axes_grid toolkit, including ParasiteAxes,
+is based on the Axisline axes. The combination of the two can be
+useful in some case. For example, you can have different tick-location,
+tick-label, or tick-formatter for bottom and top (or left and right)
+axis. ::
+
+ ax2 = ax.twin() # now, ax2 is responsible for "top" axis and "right" axis
+ ax2.set_xticks([0., .5*np.pi, np.pi, 1.5*np.pi, 2*np.pi])
+ ax2.set_xticklabels(["0", r"$\frac{1}{2}\pi$",
+ r"$\pi$", r"$\frac{3}{2}\pi$", r"$2\pi$"])
+
+
+.. plot:: mpl_toolkits/axes_grid/figures/simple_axisline4.py
+
+
+AxisLine Axes lets you create a custom axis, ::
+
+ # make new (right-side) yaxis, but wth some offset
+ offset = (20, 0)
+ new_axisline = ax.get_grid_helper().new_fixed_axis
+ ax.axis["right2"] = new_axisline(loc="right",
+ offset=offset)
+
+
+And, you can use it with parasiteAxes.
+
+
+.. plot:: mpl_toolkits/axes_grid/figures/demo_parasite_axes2.py
+
+
+AnchoredArtists
+===============
+
+It's a collection of artists whose location is anchored to the (axes)
+bbox, like the legend. It is derived from *OffsetBox* in mpl, and
+artist need to be drawn in the canvas coordinate. But, there is a
+limited support for an arbitrary transform. For example, the ellipse
+in the example below will have width and height in the data
+coordinate.
