Detailed Description¶

QXYSeries supports displaying best fit line on a chart. Best fit line is a line through a chart that expresses the relationship between points.

class PySide6.QtCharts.QXYSeries¶

PySide6.QtCharts.QXYSeries.PointConfiguration¶

This enum value describes the particular configuration of a point.

Constant

Description

QXYSeries.PointConfiguration.Color

This enum value can be used to change a point’s color. If used together with setPointConfiguration , the configuration’s value should be a valid QColor .

QXYSeries.PointConfiguration.Size

This enum value can be used to change a point’s size. If used together with setPointConfiguration , the configuration’s value should be a number, such as qreal or int.

QXYSeries.PointConfiguration.Visibility

This enum value can be used to hide or show the point. If used together with setPointConfiguration , the configuration’s value should be boolean.

QXYSeries.PointConfiguration.LabelVisibility

This enum value can be used to hide or show the label of the point. If used together with setPointConfiguration , the configuration’s value should be boolean.

PySide6.QtCharts.QXYSeries.isPointSelected(index)¶

Parameters: index – int
Return type: bool

Returns true if point at given index is among selected points and false otherwise.

Note

Selected points are drawn using the selected color if it was specified.

PySide6.QtCharts.QXYSeries.lightMarker()¶

Return type: PySide6.QtGui.QImage

Gets the image used for drawing markers on each point of the series.

The default value is QImage(), meaning no light marker will be painted.

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.

Parameters: lightMarker – PySide6.QtGui.QImage

PySide6.QtCharts.QXYSeries.markerSize()¶

See also

brush() setTheme()

PySide6.QtCharts.QXYSeries.setColor(color)¶

Parameters: color – PySide6.QtGui.QColor

This property holds The color of the series..

This is the line (pen) color in case of QLineSeries or QSplineSeries and the fill (brush) color in case of QScatterSeries or QAreaSeries .

See also

pen() brush()

PySide6.QtCharts.QXYSeries.setLightMarker(lightMarker)¶

Parameters: lightMarker – PySide6.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() ( 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.

See also

lightMarker()

PySide6.QtCharts.QXYSeries.setMarkerSize(size)¶

Parameters: size – float

Sets the size of the marker used to render points in the series.

The default size is 15.0.

See also

markerSize

PySide6.QtCharts.QXYSeries.setPen(pen)¶

Parameters: pen – PySide6.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 –

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 serie");
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::LabelVisibility);
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 red and visibly bigger than the others with a look derived from series. By default, points don’t have labels, but the point at index 4 has the label thanks to the LabelVisibility configuration value. Below is an example of a chart created in this way:

See also

pointConfiguration() pointsConfiguration() clearPointsConfiguration()

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

Parameters

index – int
key – PointConfiguration
value – object

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.

series->setPointLabelsFormat("(@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.
