<h2 id="details">Detailed Description</h2>
<p>The <a href="qsplineseries.html">QSplineSeries</a> class presents data as spline charts.</p>
<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_splinechart.png" alt="" /></p><p>The following code snippet illustrates how to create a basic spline chart:</p>
<pre class="cpp">

  <span class="type"><a href="qsplineseries.html#QSplineSeries">QSplineSeries</a></span><span class="operator">*</span> series <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qsplineseries.html#QSplineSeries">QSplineSeries</a></span>();
