title: How to insert QChartView in form with Qt Designer?
body: <p>I want to add <code>QChart</code> to the form. But I can't find it in the Widget Box. So I created it in the code. How can I insert it in <code>QWidget</code> or <code>QFrame</code> or something else?  </p>
  
  <p>I want to set area of that widget in QtDesigner.</p>
