Building
========
Please note that if you have already installed a previous version of
QtCommercial 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 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
Main Changes between 1.2.0 and 1.2.1
===================================
- Commercial Charts documentation also as *.qch file
Bug Fixes
==========
- Fixed: Crash with NaN, inf, -inf values (values are ignored)
- Fixed: Axis label truncated with multiple axis
- Fixed: Using setLineVisible(false) on a QBarCategoryAxis gives blurry text
- Fixed: Set the range to min and max for default axes from previously added series
- Fixed: Axes use incorrect bounding rectangle to calculate sizeHint when labels are in non-default angle
- Fixed: Axis titles can slightly overlap with axis labels and axis lines
- Fixed: Charts crashes when changing the values to empty model with logarithmic axis
- Fixed: The legend marker for main series in breakdown series piechart couldnt be updated with custom value
- Fixed: Positioning errors with category axis and bar category axis ticks
Known Issues
============
- Automatic scaling of the axes is only done when you add a series on a chart
- DateTimeAxis is not supported on ARM because of floating point precision
issues (qreals are floats)
- Declarative plugin is available from Qt 4.7.4 onwards because of missing
Q_REVISION macro in the earlier Qt releases
- Defining axis min-max values sometimes affects other axes with the same orientation
- See for example the secondary y-axis of QML Weather demo application
- The work-around is to set axis range dynamically instead of initializing min and
max properties to certain values
