Qt Data Visualization Known Issues
- Some platforms like Android and WinRT cannot handle multiple native windows properly, so only the Qt Quick 2 graphs are available in practice for those platforms.
 - Surfaces with non-straight rows and columns do not always render properly.
 - Q3DLight class (and Light3D QML item) are currently not usable for anything.
 - Changing most of Q3DScene properties affecting subviewports currently has no effect.
 - Widget based examples layout incorrectly in iOS.
 - Reparenting a graph to an item in another QQuickWindow is not supported.
 - Android builds of QML applications importing QtDataVisualization also require "QT += datavisualization" in the pro file. This is because Qt Data Visualization QML plugin has a dependency to Qt Data Visualization C++ library, which Qt Creator doesn't automatically add to the deployment package.
