    @SGaist If I can say this: I think its not a problem with my code. I think there is some software package for QtGraphs missing. In comparism with QtCharts, there is no

    • libQt6GraphsQml6 -> /usr/lib64/
    • qt6-graphsqml-devel -> /usr/include/qt6/QtGraphsQml/

    When I tried to use QtCharts before, the remaining prompts were also not found by QtCreator, before I installed the corresponding devel packages from the repo ...

    @Tobias83 I just realized you have 6.7. Qt Graphs went out of tech preview with 6.8.

      LineSeries

      do you have
      import QtCharts 2.8
      in Main.qml?

        Graphs went out of tech preview with 6.8

        What does that mean?

        On my Computer I have libQt6Core6 6.8.2-3.2. I thought the libs are downward compatible. Should I change

        find_package(Qt6 6.7 REQUIRED COMPONENTS Qml Core Quick Graphs)
        

        With changing in

        find_package(Qt6 6.8 REQUIRED COMPONENTS Qml Core Quick Graphs)
        

        there is no change.

          How did you install Qt ?
          Which packages do you have ?

            @SGaist I think its not up to Qt, because QtCharts worked for me. But maybe there is a devel package for qml needed as I wrote ...

              That's why I am asking how you installed Qt.

                @SGaist I have installed Qt via system installation, because I have OpenSuse Tumbleweed with KDE Plasma as OS. The packages are updated via the official repositories of OpenSuse. Qt Creator is also installed via the repos.

                  Are you able to build and run any of the Qt Graphs examples ?

                    @SGaist OK, the hellographs example is working: hellographs on https://code.qt.io
                    I tried to make the same cmakelists.txt, but I don't know, whats the difference between my project and hellographs. There are some warnings in QtCreator like:
                    qabstractaxis.h:17: Warnung: Multiple C++ types called QAbstractAxis found!

                    or

                      Are you trying to use both Qt Graphs and Qt Charts at the same time ?

                        @SGaist If I remove all the QtCharts promts in CMakeLists.txt and Main.qml, the error remains.

                          Did you nuke the build folder after these changes to ensure you start from a clean state ?

                            @SGaist I moved the build directory:

                            mv build-HardCore-Desktop-Debug/ build-HardCore-Desktop-Debug_old/
                            

                            Than I executed cmake file again, but I can't build the project and the project is not structered anymore. There is only a file list at the left site. The error in German language is:
                            :-1: Fehler: CMake-Konfiguration "Debug wurde nicht gefunden. Verfügbare Konfigurationen: "".
                            Stellen Sie sicher, dass der Wert der CMAKE_BUILD_TYPE-Variable derselbe wie der des "Build-Typ"-Felds ist.

                            ... cmake configuration Debug was not found. Ensure that the variable value CMAKE_BUILD_TYPE is the same as that of the Build Type area.

                                      Since you wrote that the example is building successfully, what about copying it and the gradually replace its content with the one from your project ?

                                        @SGaist OK, I coppied the main.qml file from the hellographs example to my project. And the GraphsView prompt was recognized. I found out, what the problem with my Main.qml was. I had to change the import commands:
                                        instead of

                                        import QtGraphs 2.12
                                        

                                        change to

                                        import QtGraphs
                                        

                                        helped (-:

                                        Thank you very much!!!

                                        But, I have still a question: How can I use the XYModelMapper? Is there a good example? The usage differs to QtCharts, specially xSection : qsizetype ...
