47 | 47 | KNOWN ISSUES |
|
|
48 | 48 | ============ |
|
|
49 | 49 | * The beta version of Qt Commercial Charts is still under development and thus |
|
|
50 | 50 | should not be used in e.g. product development |
|
|
51 | 51 | * The Charts API might change between the Beta and the first official release |
|
|
52 | 52 | * Mutliple axis are not suported at the moment. |
|
|
53 | 53 | * Logartmic, polar axis are not supported at the moment. |
|
|
54 | 54 | * If using QAbstractiItemModel derived model with QBarSeries, data manipulation |
|
|
55 | 55 | with QBarSeries/QBarSet APIs does not synchronize the data into the model |
|
|
56 | 56 | * Model support requires more thorough testing. |
|
|
57 | 57 | * Some QObject properties are missing |
|
|
58 | 58 | * Some notifications missing from QObject properties |
|
|
59 | 59 | * Legend layout does not work correctly with several labels |
|
|
60 | 60 | * Animations with Bar Charts can cause crashes in certain situations |
|
|
61 | 61 | * Automatic scaling of the axes is only done when you add a series on a chart |
|
|
62 | 62 | * The QML Bindings are still under development |
|
|
63 | 63 | * Mouse and touch interactions not complete on the QML API |
|
|
64 | 64 | * Missing documentation for QML API; the QML demo applications serve as |
|
|
65 | 65 | documentation instead |
|
|
66 | 66 | * Setting bar width is not possible on QBarSeries derived classes (the width |
|
|
67 | 67 | is affected with setMargin, but it has limitations) |
|
|
68 | 68 | * API for Animations state (signaling started, finished) and setting duration |
|
|
69 | 69 | etc. is missing |
|
|
70 | 70 | * In QBarSeries API bar margin related methods will be replaced with bar width |
|
|
71 | 71 | in final release |
|
|
72 | * OSX specific issue: after running 'make install' you need to fix the library | |
|
|
73 | location of libQtCommercialChart.1.dylib to match the actual installation | |
|
|
74 | path. For example: | |
|
|
75 | sudo install_name_tool -id | |
|
|
76 | /usr/local/Trolltech/Qt-4.8.0/lib/libQtCommercialChart.1.dylib | |
|
|
77 | /usr/local/Trolltech/Qt-4.8.0/lib/libQtCommercialChart.1.dylib | |
|
|
72 | 78 | |
|
|
73 | 79 | Main changes between Technology Preview and Beta release |
|
|
74 | 80 | ======================================================== |
|
|
75 | 81 | * QBarSeries now enables defining both values and bar placement in X-Axis. |
|
|
76 | 82 | Previous implementation of QBarSeries is now new series type: |
|
|
77 | 83 | QGroupedBarSeries |
|
|
78 | 84 | * QML API now defined and mostly implemented |
|
|
79 | 85 | * Q_PROPERTY definitions have been added to the API |
|
|
80 | 86 | * Model API refactored and moved from Series Classes to separate Model |
|
|
81 | 87 | Mapper Classes |
|
|
82 | 88 | * First version of Qt Designer plugin included |
|
|
83 | 89 | * Example for handling Gestures included (ZoomLineChart example) |
