<p>The limits on an axis can be set manually (e.g. <code class="docutils literal notranslate"><span class="pre">ax.set_xlim(xmin,</span> <span class="pre">xmax)</span></code>)
or Matplotlib can set them automatically based on the data already on the axes.
There are a number of options to this autoscaling behaviour, discussed below.</p>
<p>We will start with a simple line plot showing that autoscaling
extends the axis limits 5% beyond the data limits (-2π, 2π).</p>

<p>Arguments of the autoscale function give us precise control over the process
of autoscaling. A combination of arguments <code class="docutils literal notranslate"><span class="pre">enable</span></code>, and <code class="docutils literal notranslate"><span class="pre">axis</span></code> sets the
autoscaling feature for the selected axis (or both). The argument <code class="docutils literal notranslate"><span class="pre">tight</span></code>
sets the margin of the selected axis to zero. To preserve settings of either
<code class="docutils literal notranslate"><span class="pre">enable</span></code> or <code class="docutils literal notranslate"><span class="pre">tight</span></code> you can set the opposite one to <em>None</em>, that way
it should not be modified. However, setting <code class="docutils literal notranslate"><span class="pre">enable</span></code> to <em>None</em> and tight
to <em>True</em> affects both axes regardless of the <code class="docutils literal notranslate"><span class="pre">axis</span></code> argument.</p>
