They are untested and known to be broken, and their use has been

<p>The behavior of <code class="xref py py-obj docutils literal"><span class="pre">matplotlib.Artist.update</span></code> is slightly changed to

<p>The <code class="docutils literal"><span class="pre">matplotlib.ticker.LinearLocator</span></code> is used to define the range and
location of axis ticks when the user wants an exact number of ticks.
<code class="docutils literal"><span class="pre">LinearLocator</span></code> thus differs from the default locator <code class="docutils literal"><span class="pre">MaxNLocator</span></code>,
for which the user specifies a maximum number of intervals rather than
a precise number of ticks.</p>
<p>The view range algorithm in <code class="docutils literal"><span class="pre">matplotlib.ticker.LinearLocator</span></code> has been
changed so that more convenient tick locations are chosen. The new algorithm
returns a plot view range that is a multiple of the user-requested number of
ticks. This ensures tick marks will be located at whole integers more
consistently. For example, when both y-axes of a``twinx`` plot use
<code class="docutils literal"><span class="pre">matplotlib.ticker.LinearLocator</span></code> with the same number of ticks,
their y-tick locations and grid lines will coincide.</p>

<h4>Added set_params function to all Locator types<a class="headerlink" href="#added-set-params-function-to-all-locator-types" title="Permalink to this headline">¶</a></h4>
<p>This was a bug fix targeted at making the api for Locators more consistent.</p>
<p>In the old behavior, only locators of type MaxNLocator have set_params()
defined, causing its use on any other Locator to raise an AttributeError <em>(
aside: set_params(args) is a function that sets the parameters of a Locator
instance to be as specified within args)</em>. The fix involves moving set_params()
to the Locator class such that all subtypes will have this function defined.</p>
<p>Since each of the Locator subtypes have their own modifiable parameters, a
universal set_params() in Locator isn’t ideal. Instead, a default no-operation
function that raises a warning is implemented in Locator. Subtypes extending
Locator will then override with their own implementations. Subtypes that do
not have a need for set_params() will fall back onto their parent’s
implementation, which raises a warning as intended.</p>
<p>In the new behavior, Locator instances will not raise an AttributeError
when set_params() is called. For Locators that do not implement set_params(),
the default implementation in Locator is used.</p>

<h4>Preserve units with Text position<a class="headerlink" href="#preserve-units-with-text-position" title="Permalink to this headline">¶</a></h4>
<p>Previously the ‘get_position’ method on Text would strip away unit information
even though the units were still present. There was no inherent need to do
this, so it has been changed so that unit data (if present) will be preserved.
Essentially a call to ‘get_position’ will return the exact value from a call to
‘set_position’.</p>
<p>If you wish to get the old behaviour, then you can use the new method called
‘get_unitless_position’.</p>

<p>Interactive pan and zoom were previously implemented using a Cartesian-specific
algorithm that was not necessarily applicable to custom Axes. Three new private
methods, <code class="xref py py-meth docutils literal"><span class="pre">_get_view()</span></code>,
<code class="xref py py-meth docutils literal"><span class="pre">_set_view()</span></code>, and
<code class="xref py py-meth docutils literal"><span class="pre">_set_view_from_bbox()</span></code>, allow for custom
<code class="docutils literal"><span class="pre">Axes</span></code> classes to override the pan and zoom algorithms. Implementors of
custom <code class="docutils literal"><span class="pre">Axes</span></code> who override these methods may provide suitable behaviour for
both pan and zoom as well as the view navigation buttons on the interactive
toolbars.</p>

<p>In light of the new property cycling feature,
the Axes method <em>set_color_cycle</em> is now deprecated.
Calling this method will replace the current property cycle with
one that cycles just the given colors.</p>
<p>Similarly, the rc parameter <em>axes.color_cycle</em> is also deprecated in
lieu of the new <em>axes.prop_cycle</em> parameter. Having both parameters in
the same rc file is not recommended as the result cannot be
predicted. For compatibility, setting <em>axes.color_cycle</em> will
replace the cycler in <em>axes.prop_cycle</em> with a color cycle.
Accessing <em>axes.color_cycle</em> will return just the color portion
of the property cycle, if it exists.</p>

which implements the <code class="docutils literal"><span class="pre">legend_artists</span></code> method (a deprecation phase will
see this interface be maintained for v1.4). See
<a class="reference internal" href="../users/legend_guide.html#plotting-guide-legend"><span class="std std-ref">Legend guide</span></a> for further details. Further legend changes
include:</p>
<blockquote>
<div><ul class="simple">
<li><code class="xref py py-func docutils literal"><span class="pre">matplotlib.axes.Axes._get_legend_handles()</span></code> now returns a generator
of handles, rather than a list.</li>
<li>The <a class="reference internal" href="pyplot_api.html#matplotlib.pyplot.legend" title="matplotlib.pyplot.legend"><code class="xref py py-func docutils literal"><span class="pre">legend()</span></code></a> function’s “loc” positional
argument has been deprecated. Use the “loc” keyword instead.</li>
</ul>
</div></blockquote>
</li>
<li><p class="first">The rcParams <code class="xref py py-obj docutils literal"><span class="pre">savefig.transparent</span></code> has been added to control
default transparency when saving figures.</p>
</li>
<li><p class="first">Slightly refactored the <code class="xref py py-obj docutils literal"><span class="pre">Annotation</span></code> family. The text location in
<code class="xref py py-obj docutils literal"><span class="pre">Annotation</span></code> is now handled entirely handled by the underlying <code class="xref py py-obj docutils literal"><span class="pre">Text</span></code>
object so <code class="xref py py-obj docutils literal"><span class="pre">set_position</span></code> works as expected. The attributes <code class="xref py py-obj docutils literal"><span class="pre">xytext</span></code> and
<code class="xref py py-obj docutils literal"><span class="pre">textcoords</span></code> have been deprecated in favor of <code class="xref py py-obj docutils literal"><span class="pre">xyann</span></code> and <code class="xref py py-obj docutils literal"><span class="pre">anncoords</span></code> so
that <code class="xref py py-obj docutils literal"><span class="pre">Annotation</span></code> and <code class="xref py py-obj docutils literal"><span class="pre">AnnotaionBbox</span></code> can share a common sensibly named
api for getting/setting the location of the text or box.</p>
<blockquote>
<div><ul class="simple">
<li><code class="xref py py-obj docutils literal"><span class="pre">xyann</span></code> -> set the location of the annotation</li>
<li><code class="xref py py-obj docutils literal"><span class="pre">xy</span></code> -> set where the arrow points to</li>
<li><code class="xref py py-obj docutils literal"><span class="pre">anncoords</span></code> -> set the units of the annotation location</li>
<li><code class="xref py py-obj docutils literal"><span class="pre">xycoords</span></code> -> set the units of the point location</li>
<li><code class="xref py py-obj docutils literal"><span class="pre">set_position()</span></code> -> <code class="xref py py-obj docutils literal"><span class="pre">Annotation</span></code> only set location of annotation</li>
