Detailed Description
Vertical model mapper for box plot series.
Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series. Vertical model mapper is used to create a connection between QBoxPlotSeries and QAbstractItemModel derived model object. Model mapper maintains equal size of all the QBoxSets.
Note: used model has to support adding/removing rows/columns and modifying the data of the cells.
Property Documentation
firstBoxSetColumn : int
This property defines which column of the model is used as the data source for the first box-and-whiskers set.
Default value is: -1 (invalid mapping)
Access functions:
| int | firstBoxSetColumn() const |
| void | setFirstBoxSetColumn(int firstBoxSetColumn) |
Notifier signal:
| void | firstBoxSetColumnChanged() |
firstRow : int
This property defines which row of the model contains the first values of the QBoxSets in the series.
Minimal and default value is: 0
Access functions:
| int | firstRow() const |
| void | setFirstRow(int firstRow) |
Notifier signal:
| void | firstRowChanged() |
lastBoxSetColumn : int
This property defines which column of the model is used as the data source for the last box-and-whiskers set.
Default value is: -1 (invalid mapping)
Access functions:
| int | lastBoxSetColumn() const |
| void | setLastBoxSetColumn(int lastBoxSetColumn) |
Notifier signal:
| void | lastBoxSetColumnChanged() |
model : QAbstractItemModel *
This property defines the model that is used by the mapper.
Access functions:
| QAbstractItemModel * | model() const |
| void | setModel(QAbstractItemModel *model) |
Notifier signal:
| void | modelReplaced() |
rowCount : int
This property defines the number of rows of the model that are mapped as the data for QBoxPlotSeries.
Minimal and default value is: -1 (count limited by the number of rows in the model)
Access functions:
| int | rowCount() const |
| void | setRowCount(int rowCount) |
Notifier signal:
| void | rowCountChanged() |
series : QBoxPlotSeries *
This property defines the QBoxPlotSeries object that is used by the mapper.
All the data in the series is discarded when it is set to the mapper. When new series is specified the old series is disconnected (it preserves its data)
Access functions:
| QBoxPlotSeries * | series() const |
| void | setSeries(QBoxPlotSeries *series) |
Notifier signal:
| void | seriesReplaced() |
Member Function Documentation
QVBoxPlotModelMapper::QVBoxPlotModelMapper(QObject *parent = Q_NULLPTR)
