KNOWN ISSUES
|
|
|
============
|
|
|
* The beta version of Qt Commercial Charts is still under development and thus
|
|
|
should not be used in e.g. product development
|
|
|
* The Charts API might change between the Beta and the first official release
|
|
|
* Mutliple axis are not suported at the moment.
|
|
|
* Logartmic, polar axis are not supported at the moment.
|
|
|
* If using QAbstractiItemModel derived model with QBarSeries, data manipulation
|
|
|
with QBarSeries/QBarSet APIs does not synchronize the data into the model
|
|
|
* Model support requires more thorough testing.
|
|
|
* Some QObject properties are missing
|
|
|
* Some notifications missing from QObject properties
|
|
|
* Legend layout does not work correctly with several labels
|
|
|
* Animations with Bar Charts can cause crashes in certain situations
|
|
|
* Automatic scaling of the axes is only done when you add a series on a chart
|
|
|
* The QML Bindings are still under development
|
|
|
* Mouse and touch interactions not complete on the QML API
|
|
|
* Missing documentation for QML API; the QML demo applications serve as
|
|
|
documentation instead
|
|
|
* Setting bar width is not possible on QBarSeries derived classes (the width
|
|
|
is affected with setMargin, but it has limitations)
|
|
|
* API for Animations state (signaling started, finished) and setting duration
|
|
|
etc. is missing
|
|
|
* In QBarSeries API bar margin related methods will be replaced with bar width
|
|
|
in final release
|
|
|
|
|
|
Main changes between Technology Preview and Beta release
|
|
|
========================================================
|
|
|
* QBarSeries now enables defining both values and bar placement in X-Axis.
|
|
|
Previous implementation of QBarSeries is now new series type:
|
|
|
QGroupedBarSeries
|
|
|
* QML API now defined and mostly implemented
|
|
|
* Q_PROPERTY definitions have been added to the API
|
|
|
* Model API refactored and moved from Series Classes to separate Model
|
|
|
Mapper Classes
|
|
|
* First version of Qt Designer plugin included
|
|
|
* Example for handling Gestures included (ZoomLineChart example)
