----------------------------------- Qt Data Visualization 1.0.0 (beta) ----------------------------------- Qt Data Visualization module provides multiple graph types to visualize data in 3D space both with C++ and Qt Quick 2. System Requirements =================== - Qt 5.2 or newer - OpenGL 2.1 or newer (recommended) or OpenGL ES2 (reduced feature set) Platform specific recommendations: - Mac: OSX 10.8 or later recommended Building ======== Configure the project with qmake: qmake After running qmake, build the project with make: (Linux) make (Windows with MinGw) mingw32-make (Windows with Visual Studio) nmake (OSX) make The above generates the default makefiles for your configuration, which is typically the release build if you are using precompiled binary Qt distribution. To build both debug and release, or one specifically, use one of the following qmake lines instead. For debug builds: qmake CONFIG+=debug make or qmake CONFIG+=debug_and_release make debug For release builds: qmake CONFIG+=release make or qmake CONFIG+=debug_and_release make release For both builds (Windows/Mac only): qmake CONFIG+="debug_and_release build_all" make After building, install the module to your Qt directory: make install If you want to uninstall the module: make uninstall Building as a statically linked library ======================================= The same as above applies, you will just have to add static to the CONFIG: qmake CONFIG+=static Documentation ============= Pregenerated documentation can be found from doc folder for both Qt Assistant (qtdatavisualization.qch) and in HTML format (qtdatavisualization subfolder). The documentation can also be generated with: make docs Please refer to the generated documentation for more information: doc/qtdatavisualization/index.html Known Issues ============ - All other QML elements are drawn on top of the Qt DataVisualization graphs, including the parent elements of the graphs. To ensure the graphs are not hidden, make sure you don't draw anything opaque on top of the graphs. For example, Qt Creator application wizard for Qt Quick 2 applications creates by default an opaque white Rectangle element as the main element, which covers any graph added to it. - Android doesn't support both widgets and OpenGL simultaneously, so only the Qt Quick 2 API is usable in practice in Android. - Shadows are not supported with OpenGL ES2 (including Angle builds in Windows). - Anti-aliasing doesn't work with OpenGL ES2 (including Angle builds in Windows). - Surfaces with non-straight rows and columns do not always render properly. - Q3DLight class (and Light3D QML item) are currently not usable for anything. - Q3DScene::secondarySubviewOnTop property has currently no effect. - The color style Q3DTheme::ColorStyleObjectGradient doesn't work for surface graphs. - Scatter "point" meshes do not support gradients, they always use the base color. - Widget based examples layout incorrectly in iOS.
