Qt Graphs lacking functionalities - Axes range

@cristian-adam this is for the old module Qt Charts, not Qt Graphs.

Sorry. My bad. The Qt Graphs examples at https://code.qt.io/cgit/qt/qtgraphs.git/tree/examples they all have the
qmlpart. -
I had a play with the examples installed in Qt\Examples\Qt-6.10.0\graphs\2d with Qt 6.10 and was a bit underwhelmed.
quickwidgetgraphs doesn't work, nothing happens when you click on the buttons:
hellographs is QML in a QQuickView .
cockpit isn't relevant for me.
Is QtGraphs going to have a C++/widget API similar to QCharts (even if it is just a wrapper over the QML)? Or are people expected to throw away all the QtCharts/widget code and rewrite it all from scratch in QtGraphs/QML?

The *.pro file is broken in Qt 6.10.0 (it's fixed for the next releases). Load the CMakeLists.txt and it will work.
I also suggest downloading the latest version of the example (it's not released yet so get it via git): https://github.com/qt/qtgraphs/tree/dev/examples/graphs/2d/quickwidgetgraphs This shows you how to use Qt Graphs without writing any QML code.

I managed to get https://github.com/qt/qtgraphs/tree/dev/examples/graphs/2d/quickwidgetgraphs . It seems somewhat more convoluted than the QtCharts equivalent.
Is there going to be a simple migration path from QtCharts to QtGraphs?
How long is QtCharts going to be supported?

I ported a simple app (where the data points were written in C++ but displayed in QML/Qt Quick) from Qt Charts to Qt Graphs in Qt 6.10.0. There were some differences in how we set up
ChartsViewvs.GraphsView, but I did not have to make any changes to my C++ code (QLineSeries).Note: There are differences in the C++ API too, but I hadn't used the parts that changed. Depending on the complexity of your existing code, migration could be simple.

Can you please describe which part(s) you found more convoluted, and how it could be simplified?
How long is QtCharts going to be supported?
Qt Charts has been deprecated, meaning that it will no longer receive new features or minor bugfixes. However, it should continue to be available for the lifetime of Qt 6 (removed from Qt 7).

Ok, thanks.

It seems to have more classes involved. But it is a while since I looked at QtCharts.

Hopefully, it will still be supported in a Qt6Compat module in Qt 7.

Thanks @mklisiewicz for bringing this into our attention. -
Hi, I just installed QT Creator for testing Charts and Graphs,
and it seems that Graphs has disappeared, as well as the examples !?
Do I have to install Graphs manually ? Or do I miss something ? I reinstalled Qt to be sure but I could see no specific option
I downloaded/installed an example manually but no luck (see bug report below)Charts: I tested examples ChartsGallery and ZoomLineChart:
both work fine, but :- Charts depreciated according to docs, so it will probably disappear soon
- chart is not visible in design mode
(Are there any 3rd party extensions for plotting data ?)
Thanks in advance for any suggestions.
