    Hi.
    Ich habe Qt Charts installiert. habe sogar #include <QLineSeries> geschrieben. Innerhalb meiner Funktion void Mainwindow::diagram () {
    QLineSeries *series = new QLineSeries();
    }
    kennt er QLineSeries aber nicht.. Warum?

    I have installed Qt Charts. I included #include <QLineSeries> which is auto detecting by Qt Creator. I also include QT += charts in the .pro file.

    Now I have the function

    void MainWindow::Diagramm() {
     QLineSeries *series = new QLineSeries();
    }
    

    Here he don't know about QLineSeries. Why?

    Danke,
    Thank you,

    Henrik

      Maybe you forgot to add QT += charts to your project file?

          It works
          I replace

          #include <QSeriesLine>
          

          to

          #include <QtCharts/QLineSeries>
