Unknown type name 'Q3DScatter'

[zbysekvoda]

I want to create app solving Lorenz Attractor.

In left window (QGraphicsView) i would like to have 3DScatter plot.

I am trying to utilize example https://doc.qt.io/qt-5.11/qtdatavisualization-scatter-example.html, but I fail on first step:

Q3DScatter *graph = new Q3DScatter();

Editor says Unknown type name 'Q3DScatter'.

I have tried

#include <Q3DScatter>

and

#include <QtDataVisualization/Q3DScatter>

but nothing helped.

I can compile and run example https://doc.qt.io/qt-5.11/qtdatavisualization-scatter-example.html without problems.

Can someone give me a hint? Thank you in advance.

I forget to note that I am using MacOS Mojave 10.14 and I have Qt 5.9 (I need this version because of compatibility with school server)

hi
You need to add
QT += datavisualization
to .pro and rerun qmake
