Building
========
Configure project with qmake:
qmake CONFIG+=release
Build poject with make:
(Linux) make
(Windows with MinGw) mingw32-make
(Visual Studio) nmake
If you want to install the libraries to your Qt library directory use:
make install
If you want to uninstall the libraries
make uninstall
Documentation
=============
The documentation can be generated with "make docs". It will be placed
into "doc/html" in the build directory.
KNOWN ISSUES
============
* The beta version of Qt Commercial Charts is still under development and thus
should not be used in e.g. product development
* The Charts API might change between the Beta and the first official release
* Mutliple axis are not suported at the moment.
* Logartmic, polar axis are not supported at the moment.
* If using QAbstractiItemModel derived model with QBarSeries, data manipulation
with QBarSeries/QBarSet APIs does not synchronize the data into the model
* Model support requires more thorough testing.
* Some QObject properties are missing
* Some notifications missing from QObject properties
* Legend layout does not work correctly with several labels
* Animations with Bar Charts can cause crashes in certain situations
* Automatic scaling of the axes is only done when you add a series on a chart
* The QML Bindings are still under development
* Mouse and touch interactions not complete on the QML API
* Missing documentation for QML API; the QML demo applications serve as
documentation instead
* Setting bar width is not possible on QBarSeries derived classes (the width
is affected with setMargin, but it has limitations)
* API for Animations state (signaling started, finished) and setting duration
etc. is missing
* In QBarSeries API bar margin related methods will be replaced with bar width
in final release
* OSX specific issue: after running 'make install' you need to fix the library
location of libQtCommercialChart.1.dylib to match the actual installation
path. For example:
sudo install_name_tool -id
/usr/local/Trolltech/Qt-4.8.0/lib/libQtCommercialChart.1.dylib
/usr/local/Trolltech/Qt-4.8.0/lib/libQtCommercialChart.1.dylib
Main changes between Technology Preview and Beta release
========================================================
* QBarSeries now enables defining both values and bar placement in X-Axis.
Previous implementation of QBarSeries is now new series type:
QGroupedBarSeries
* QML API now defined and mostly implemented
* Q_PROPERTY definitions have been added to the API
* Model API refactored and moved from Series Classes to separate Model
Mapper Classes
* First version of Qt Designer plugin included
* Example for handling Gestures included (ZoomLineChart example)
