How to insert QChartView in form with Qt Designer?

Question

I want to add QChart 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 QWidget or QFrame or something else?

I want to set area of that widget in QtDesigner.

Answer 1

Let me add something here for the answer below (thanks for that!)
I had some additional steps for using

QTcreator 4.11.0

on

Ubuntu 20.04.3 LTS

First, you need to install not only package

qml-module-qtcharts

But also package

libqt5charts5-dev

Next, for "Option 1: Promoted" below you 1st have to use Button "Add" after entering

Promoted class name: QChartView

and

Header file: QtCharts

Then, you can select it from the "Promoted Classes"

Finally, QTCreator adds to your ui_mainwindow.h (e.g.)

#include <qchartview.h>

and uses

QChartView *graphicsView;

But it does not consider, that type QChartView is defined in "namespace QtCharts" in <qchartview.h>. Therefore, type QChartView is not found.

I fixed (hacked) this by adding a "Central.h" to #include for users as a 1st #include file, with content

#ifndef CENTRAL_H
#define CENTRAL_H

#include <QtCharts>
using namespace QtCharts;

#endif // CENTRAL_H
