Building
========
Please note that if you have already installed a previous version of
Qt Charts, you should first uninstall it with
make uninstall
Configure project with qmake and build project with make:
(Linux) make
(Windows with MinGw) mingw32-make
(Visual Studio) nmake
(OSX) make
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:
qmake CONFIG+="debug_and_release build_all"; make
If you want to leave out demos and examples from the build you can use
the following config with qmake:
CONFIG+=nomake_demos_examples
For some embedded environments, such as VxWorks, all examples and demos
may not be applicable. There it's recommended to use the above mentioned
config option.
If you want to install the libraries to your Qt library directory use:
make install
If you want to uninstall the libraries:
make uninstall
Building as a statically linked library
=======================================
The same as above applies, you will just have to add staticlib to the CONFIG:
qmake CONFIG+=staticlib
Documentation
=============
Documentation can be found from doc/html and doc/qch directories. The documentation
can also be generated with:
make docs
The documentation provided with Charts is generated with qdoc and the creation of the
documentation is prioritized for Qt5. We recommend building the documentation using Qt5,
if you want to do it yourself. Creating the documentation using Qt4 also works, but some
pages are not generated correctly, such as the 'List of All Members' page for all C++ and
QML APIs in .qch documentation.
Main Changes between 1.3.1 and 1.4.0
====================================
- New: Added possibility to set brush image for AreaSeries, BarSet, BoxPlotSeries,
BoxSet, PieSlice and ScatterSeries by specifying 'brushFilename'
- New: Added possibility to show series point values for line, spline and scatter series
- New: Added possibility to position the bar value labels
Bug Fixes and minor new features
================================

- New: Install the plugins.qmltypes file for Qt Quick 2 requested by Qt Creator
- New: Added clear function for BarCategoryAxis
- Fixed: Assert failure with percent bar series zero values
- Fixed: Updated files generated with Qt Creator for demos
- Fixed: DeclarativeChart::legend property marked as constant
