How to integrate a Q3DScatter graph into a Widget in a Main Window?

Reda94

I'm trying to display a Q3DScatter graph in a Main Window designed with Qt Designer so I've added a widget to the main window but I don't know how to embed the graph object in this widget. I tried to create a widget "container" programmatically and embed the graph in it and then putting the widget in a QHBoxLayout (which has been added to the main window using Qt Designer) using the following code in my main window's constructor:

...
Q3DScatter *graph = new Q3DScatter();
QWidget *container = QWidget::createWindowContainer(graph);
ui->horizontal_layout->addWidget(container, 1);

But the window appears to be empty when executing. I'd really appreciate some help.

Code looks correct but you are not adding any series to the scatter... that's why it's empty

Q3DScatter *graph = new Q3DScatter();

 QScatter3DSeries *series = new QScatter3DSeries;
    QScatterDataArray data;
    data << QVector3D(0.5f, 0.5f, 0.5f) << QVector3D(-0.3f, -0.5f, -0.4f) << QVector3D(0.0f, -0.3f, 0.2f);
    series->dataProxy()->addItems(data);
    graph->addSeries(series);
QWidget *container = QWidget::createWindowContainer(graph,this);
ui->horizontal_layout->addWidget(container);

@VRonin Thanks for answering! I've tried your code but it's still not showing the graph, here's the full code of my main window constructor:

ResultsWindow::ResultsWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::ResultsWindow)
{
ui->setupUi(this);
Q3DScatter *graph = new Q3DScatter();

 QScatter3DSeries *series = new QScatter3DSeries;
 QScatterDataArray data;
 data << QVector3D(0.5f, 0.5f, 0.5f) << QVector3D(-0.3f, -0.5f, -0.4f) << QVector3D(0.0f, -0.3f, 0.2f);
 series->dataProxy()->addItems(data);
 graph->addSeries(series);
QWidget *container = QWidget::createWindowContainer(graph,this);
ui->h_graph->addWidget(container);

}

The layout which is supposed to contain the graph appears empty.
