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()
