------------------------------------------------- Qt Data Visualization 0.1.0 (Techonology preview) ------------------------------------------------- Qt Data Visualization module provides multiple graph types to visualize data in 3D space both with C++ and Qt Quick 2. System Requirements =================== - Qt 5.1 or newer - OpenGL 2.1 or newer (recommended) or OpenGL ES2 (reduced feature set) Building ======== Configure project with qmake and build project with make: (Linux) make (Windows with MinGw) mingw32-make (Visual Studio) nmake (OSX) make If you want to install the module to your Qt directory use: 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/qtdatavisualization-index.html Known Issues ============ The technology preview version is still missing some features entirely, while some others may be only partially implemented. Here are some known issues: - Scatter graphs can only show zero centered axis ranges properly. - Value axis range of a bar graph with negative values need to be zero centered to display properly. - Selection API is missing for surface graphs. - Shadows do not work for surface graphs. - Mac: Graphs drawn half the size on Retina displays. - Using multiple graphs in one application crashes on application shutdown unless the last graph to have active context is deleted last. - Android doesn't support both widgets and OpenGL simulataneously, 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).
