QtCharts
Model mappers enable using a data model derived from the QAbstractItemModel class as a data source for a chart.
Member Function Documentation
[protected]
int QBarModelMapper::count() const
Returns the number of rows/columns of the model that are mapped as the data for QAbstractBarSeries Minimal and default value is: -1 (count limited by the number of rows/columns in the model)
See also setCount().
[protected]
int QBarModelMapper::first() const
Returns which row/column of the model contains the first values of the QBarSets in the series. The default value is 0.
See also setFirst().
[protected]
int QBarModelMapper::firstBarSetSection() const
Returns which section of the model is used as the data source for the first bar set
See also setFirstBarSetSection().
[protected]
int QBarModelMapper::lastBarSetSection() const
Returns which section of the model is used as the data source for the last bar set
See also setLastBarSetSection().
[protected]
Qt::Orientation QBarModelMapper::orientation() const
Returns the orientation that is used when QBarModelMapper accesses the model. This mean whether the consecutive values of the bar set are read from row (Qt::Horizontal) or from columns (Qt::Vertical)
See also setOrientation().
[protected]
void QBarModelMapper::setCount(int count)
Sets the count of rows/columns of the model that are mapped as the data for QAbstractBarSeries Minimal and default value is: -1 (count limited by the number of rows/columns in the model)
See also count().
[protected]
void QBarModelMapper::setFirst(int first)
Sets which row of the model contains the first values of the QBarSets in the series. The default value is 0.
See also first().
[protected]
void QBarModelMapper::setFirstBarSetSection(int firstBarSetSection)
Sets the model section that is used as the data source for the first bar set Parameter firstBarSetSection specifies the section of the model.
See also firstBarSetSection().
[protected]
void QBarModelMapper::setLastBarSetSection(int lastBarSetSection)
Sets the model section that is used as the data source for the last bar set Parameter lastBarSetSection specifies the section of the model.
See also lastBarSetSection().
[protected]
void QBarModelMapper::setOrientation(Qt::Orientation orientation)
Returns the orientation that is used when QBarModelMapper accesses the model. This mean whether the consecutive values of the pie are read from row (Qt::Horizontal) or from columns (Qt::Vertical)
See also orientation().
