<p>Some people prefer to write more pythonic, object-oriented code

rather than use the pyplot interface to matplotlib. This example shows

you how.</p>

<p>Unless you are an application developer, I recommend using part of the

pyplot interface, particularly the figure, close, subplot, axes, and

show commands. These hide a lot of complexity from you that you don't

need to see in normal figure creation, like instantiating DPI

instances, managing the bounding boxes of the figure elements,

creating and realizing GUI windows and embedding figures in them.</p>

<p>If you are an application developer and want to embed matplotlib in

your application, follow the lead of examples/embedding_in_wx.py,

examples/embedding_in_gtk.py or examples/embedding_in_tk.py. In this

case you will want to control the creation of all your figures,

embedding them in application windows, etc.</p>

<p>If you are a web application developer, you may want to use the

example in webapp_demo.py, which shows how to use the backend agg

figure canvas directly, with none of the globals (current figure,

current axes) that are present in the pyplot interface. Note that

there is no reason why the pyplot interface won't work for web

application developers, however.</p>

<p>If you see an example in the examples dir written in pyplot interface,

and you want to emulate that using the true python method calls, there

is an easy mapping. Many of those examples use 'set' to control

figure properties. Here's how to map those commands onto instance

methods</p>

<p>The syntax of set is:</p>

<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">plt</span><span class="o">.</span><span class="n">setp</span><span class="p">(</span><span class="nb">object</span> <span class="ow">or</span> <span class="n">sequence</span><span class="p">,</span> <span class="n">somestring</span><span class="p">,</span> <span class="n">attribute</span><span class="p">)</span>

</pre></div>

</div>

<p>if called with an object, set calls:</p>

<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="nb">object</span><span class="o">.</span><span class="n">set_somestring</span><span class="p">(</span><span class="n">attribute</span><span class="p">)</span>

</pre></div>

</div>

<p>if called with a sequence, set does:</p>

<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="k">for</span> <span class="nb">object</span> <span class="ow">in</span> <span class="n">sequence</span><span class="p">:</span>

<span class="nb">object</span><span class="o">.</span><span class="n">set_somestring</span><span class="p">(</span><span class="n">attribute</span><span class="p">)</span>

</pre></div>

</div>

<p>So for your example, if a is your axes object, you can do:</p>

<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">a</span><span class="o">.</span><span class="n">set_xticklabels</span><span class="p">([])</span>

<span class="n">a</span><span class="o">.</span><span class="n">set_yticklabels</span><span class="p">([])</span>

<span class="n">a</span><span class="o">.</span><span class="n">set_xticks</span><span class="p">([])</span>

<span class="n">a</span><span class="o">.</span><span class="n">set_yticks</span><span class="p">([])</span>

</pre></div>

</div>
