<h2 id="details">Detailed Description</h2>
<p>The <a href="qml-qtcharts-barcategoryaxis.html">BarCategoryAxis</a> type can be set up to show an axis line with tick marks, grid lines, and shades. Categories are drawn between the ticks. It can be used also with a line series.</p>
<p>The following QML snippet illustrates how to use <a href="qml-qtcharts-barcategoryaxis.html">BarCategoryAxis</a>:</p>
<pre class="cpp">

  ChartView {
      BarCategoryAxis {
          id: categoryAxis
          categories: <span class="operator">[</span><span class="string">&quot;Jan&quot;</span><span class="operator">,</span> <span class="string">&quot;Feb&quot;</span><span class="operator">,</span> <span class="string">&quot;Mar&quot;</span><span class="operator">,</span> <span class="string">&quot;Apr&quot;</span><span class="operator">,</span> <span class="string">&quot;May&quot;</span><span class="operator">,</span> <span class="string">&quot;Jun&quot;</span> <span class="operator">]</span>
