<h2 id="details">Detailed Description</h2>
<p>A spline series stores the data points and the segment control points needed by QPainterPath to draw a spline. The control points are automatically calculated when the data changes. The algorithm computes the points so that the normal spline can be drawn.</p>
<p class="centerAlign"><img src="images/examples_qmlchart3.png" alt="" /></p><p>The following QML code shows how to create a simple spline chart:</p>
