<h2 id="details">Detailed Description</h2>
<p>The <a href="qml-qtcharts-valueaxis.html">ValueAxis</a> type can be set up to show an axis line with tick marks, grid lines, and shades. The values on the axis are drawn at the positions of tick marks.</p>
<p>The following example code illustrates how to use the <a href="qml-qtcharts-valueaxis.html">ValueAxis</a> type:</p>
<pre class="cpp">

  ChartView {
      ValueAxis {
          id: xAxis
          min: <span class="number">0</span>
          max: <span class="number">10</span>
      }
  <span class="comment">// Add a few series...</span>
