PySide6.QtGraphs.QXYModelMapper¶

class QXYModelMapper¶

The QXYModelMapper class is a model mapper for line, spline, and scatter series. More…

Added in version 6.8.

Synopsis¶

Properties¶

countᅟ - Number of rows of the model that are mapped as the data for series
firstᅟ - Row of the model that contains the data for the first point of the series
modelᅟ - That is used by the mapper
orientationᅟ - Tells the modelmapper how to map data from a model. If Qt::Vertical is used, each of the model’s columns defines a bar set, and the model’s rows define the categories. When the orientation is set to Qt::Horizontal, each of the model’s rows defines a bar set, and the model’s columns define categories
seriesᅟ - That is used by the mapper
xSectionᅟ - Section of the model that contains the x-coordinates of data points
ySectionᅟ - The section of the model that contains the y-coordinates of data points

Detailed Description¶

Model mappers enable using a data model derived from the QAbstractItemModel class as a data source for a graph. A model mapper is used to create a connection between a line, spline, or scatter series. A TableModel is a natural choice for the model.

Both model and series properties can be used to manipulate the data. The model mapper keeps the series and the data model in sync.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property countᅟ: int¶

This property holds The number of rows of the model that are mapped as the data for series..

The minimum and default value is -1 (the number is limited by the number of rows in the model).

See also

orientation

Access functions:

count()
setCount()
Signal countChanged()

property firstᅟ: int¶

This property holds The row of the model that contains the data for the first point of the series..

The minimum and default value is 0.

See also

orientation

Access functions:

first()
setFirst()
Signal firstChanged()

property modelᅟ: QAbstractItemModel¶

This property holds The model that is used by the mapper..

Access functions:

model()
setModel()
Signal modelChanged()

property orientationᅟ: Qt.Orientation¶

This property holds Tells the modelmapper how to map data from a model. If Qt::Vertical is used, each of the model’s columns defines a bar set, and the model’s rows define the categories. When the orientation is set to Qt::Horizontal, each of the model’s rows defines a bar set, and the model’s columns define categories..

The default value is Qt::Vertical

Access functions:

orientation()
setOrientation()
Signal orientationChanged()

property seriesᅟ: QXYSeries¶

This property holds The series that is used by the mapper..

All the data in the series is discarded when it is set to the mapper. When a new series is specified, the old series is disconnected (but it preserves its data).

Access functions:

series()
setSeries()
Signal seriesChanged()

property xSectionᅟ: int¶

This property holds The section of the model that contains the x-coordinates of data points..

The default value is -1 (invalid mapping).

See also

orientation

Access functions:

xSection()
setXSection()
Signal xSectionChanged()

property ySectionᅟ: int¶

This property holds the section of the model that contains the y-coordinates of data points..

The default value is -1 (invalid mapping).

See also

orientation

Access functions:

ySection()
setYSection()
Signal ySectionChanged()
