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 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 1.2.1 and 1.3.0
|
|
|
====================================
|
|
|
|
|
|
- New chart type added: Polar chart
|
|
|
- New series type added: Box and whiskers
|
|
|
- QtQuick 2 support added
|
|
|
- Note: Since Qt Charts still uses QGraphicsView framework under the hood
|
|
|
even with QtQuick 2, its performance is actually better with QtQuick 1 than with QtQuick 2.
|
|
|
|
|
|
Bug Fixes and minor new features
|
|
|
================================
|
|
|
|
|
|
- New: Added missing QML support for LogValueAxis
|
|
|
- New: Implement index based removing/replacing points in a series
|
|
|
- New: Added API to specify plot area background for the chart
|
|
|
- New: Added HTML support for various text items such as axis labels or titles
|
|
|
- HTML tags (e.g. <br/>) and character codes (e.g. °) are now supported
|
|
|
- Setting pen for text items is deprecated and does nothing
|
|
|
- When setting brush for text items, only the color of the brush is relevant.
|
|
|
It specifies the default text color for the item.
|
|
|
- Logic for identifying axis label format specifiers was improved, so adding
|
|
|
additional information to labels via label format string is now more viable.
|
|
|
- New: Added QChart::zoomReset() and QChart::isZoomed()
|
|
|
- New: Added API for setting roundness of the corners for the background of the chart
|
|
|
- Fixed: If vertical QLogValueAxis base is selected so that it has only single visible tick,
|
|
|
its label always displays as "..."
|
|
|
- Fixed: Crash when removing pie series from chart
|
|
|
- Fixed: Most themes disable axis shades
|
|
|
- Fixed: Lingering shades from high contrast theme
|
|
|
- Fixed: Crash when adding/removing points during animation
|
|
|
- Fixed: Wrong expand direction with rotated chart view
|
|
|
- Fixed: Android build errors
|
|
|
- Fixed: Explicitly set default pen/brush/font got overridden by theme
|
|
|
- Default pens, brushes, and fonts were changed to ones that won't clash with commonly
|
|
|
used types of the same. Most notably black pen is no longer default and won't anymore
|
|
|
get overridden by theme if used.
|
|
|
- Fixed: Multi-line axis titles and labels now position correctly
|
|
|
- Note that '\n' no longer causes new line in text items, use HTML tag <br/> instead
|
|
|
- Fixed: Legend markers text truncation with small font sizes
|
|
|
- Fixed: QChartView right click zoom out when zooming only along one axis
|
|
|
- Fixed: Crash or memory leak when resetting animation options mid-animation
|
|
|
- Fixed: QBarCategoryAxis doesn't notify domain on category remove
|
|
|
- Fixed: axisXTop QML property now actually puts axis on top
|
