    #include <QApplication>
    #include <QMainWindow>
    #include <QtCharts>
    #include <QNetworkAccessManager>
    #include <QNetworkReply>
    #include <QJsonDocument>
    #include <QJsonObject>
    #include <QJsonArray>
    
    using namespace QtCharts; //error here
    

    why does it give such an error, qtcharts is connected, but nothing works

    error: Expected namespace name
