Access functions:
property PᅟySide6.QtCharts.QXYSeries.pointLabelsClipping: bool#

This property holds The clipping for data point labels..

This property is true by default. The labels on the edge of the plot area are cut when clipping is enabled.

Access functions:
property PᅟySide6.QtCharts.QXYSeries.pointLabelsColor: PySide6.QtGui.QColor#

This property holds The color used for data point labels. By default, the color is the color of the brush defined in theme for labels..

Access functions:

The index in the series of the data point. [since 6.5]

@xPoint

The x-coordinate of the data point.

@yPoint

The y-coordinate of the data point.

For example, the following usage of the format tags would produce labels that display the data point shown inside brackets separated by a comma (x, y):

series->setPointLabelsFormat("@index: (@xPoint, @yPoint)");

By default, the labels’ format is set to @xPoint, @yPoint. The labels are shown on the plot area, and the labels on the edge of the plot area are cut. If the points are close to each other, the labels may overlap.

The light markers visualize the data points of this series and as such are an alternative to setPointsVisible (true). Both features can be enabled independently from each other.

Unlike the elements of QScatterSeries the light markers are not represented by QGraphicsItem, but are just painted (no objects created). However, the mouse-event-signals of QXYSeries behave the same way, meaning that you’ll get the exact domain value of the point if you click/press/hover the light marker. You’ll still get the in between domain value if you click on the line. The light markers are above the line in terms of painting as well as events.

PySide6.QtCharts.QXYSeries.setColor(color)#
Parameters:

colorPySide6.QtGui.QColor

See also

color()

Setter of property color .

PySide6.QtCharts.QXYSeries.setLightMarker(lightMarker)#
Parameters:

lightMarkerPySide6.QtGui.QImage

Sets the image used for drawing markers on each point of the series as the value of lightMarker.

The default value is a default-QImage() (QImage::isNull() == true), meaning no light marker will be painted. You can reset back to default (disabled) by calling this function with a null QImage (QImage()).

The light markers visualize the data points of this series and as such are an alternative to setPointsVisible(true). If a light marker is set with this method, visible points as set with setPointsVisible(true) are not displayed.

Unlike the elements of QScatterSeries the light markers are not represented by QGraphicsItem, but are just painted (no objects created). However, the mouse-event-signals of QXYSeries behave the same way, meaning that you’ll get the exact domain value of the point if you click/press/hover the light marker. You’ll still get the in between domain value if you click on the line. The light markers are above the line in terms of painting as well as events.

lightMarker()

PySide6.QtCharts.QXYSeries.setMarkerSize(size)#
Parameters:

size – float

PySide6.QtCharts.QXYSeries.setPen(pen)#
Parameters:

penPySide6.QtGui.QPen

Sets the pen used for drawing points on the chart to pen. If the pen is not defined, the pen from the chart theme is used.

See also

pen() setTheme()

PySide6.QtCharts.QXYSeries.setPointConfiguration(index, configuration)#
Parameters:
  • index – int

  • configuration – Dictionary with keys of type .QXYSeries.PointConfiguration and values of type QVariant.

Enables customizing the appearance of a point located at index with desired configuration.

With points configuration you can change various aspects of every point’s appearance.

A point’s configuration is represented as a hash map with pointConfiguration keys and QVariant values. For example:

QLineSeries *series = new QLineSeries();
series->setName("Customized series");
series->setPointsVisible(true);

*series << QPointF(0, 6) << QPointF(2, 4) << QPointF(3, 6) << QPointF(7, 4) << QPointF(10, 5)
        << QPointF(11, 1) << QPointF(13, 3) << QPointF(17, 6) << QPointF(18, 3)
        << QPointF(20, 2);

QChart *chart = new QChart();
chart->addSeries(series);
chart->createDefaultAxes();

QHash<QXYSeries::PointConfiguration, QVariant> conf;
conf[QXYSeries::PointConfiguration::Color] = QColor(Qt::red);
conf[QXYSeries::PointConfiguration::Size] = 8;
conf[QXYSeries::PointConfiguration::LabelVisibility] = true;

series->setPointConfiguration(4, conf);

conf.remove(QXYSeries::PointConfiguration::Color);
conf[QXYSeries::PointConfiguration::LabelFormat] = "This Point";
series->setPointConfiguration(6, conf);

In this example, you can see a default QLineSeries with 10 points and with changed configuration of two points. Both changed points are visibly bigger than the others with a look derived from the series configuration. By default, points don’t have labels, but the point at index 4 has a label thanks to the LabelVisibility and LabelFormat configuration values. The point at index 6 has a custom label This Point thanks to the LabelFormat configuration value. Below is an example of a chart created in this way:

PySide6.QtCharts.QXYSeries.setPointConfiguration(index, key, value)
Parameters:

Enables customizing a particular aspect of a point’s configuration.

Note

Points configuration concept provides a flexible way to configure various aspects of a point’s appearance. Thus, values need to have an elastic type such as QVariant. See PointConfiguration to see what value should be passed for certain key.
