      Description

      I work on Windows 10, ide - Qt Creator, compiler - Visual Studio 2017.

      I am testing "LineChart Example" https://doc.qt.io/qt-5/qtcharts-linechart-example.html#

      I change data in this one. I can see a good result.

      If uncomment line

      //series->setUseOpenGL(true); //don'n work!
