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 directory. The documentation
|
|
|
can also be generated with:
|
|
|
make docs
|
|
|
|
|
|

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
|
|
|
|
|
|
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
