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
|
|
|
|

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
