Detailed Description#
An area series is used to show quantitative data. It is based on a line series, in the way that the area between the boundary lines is emphasized with color. Since the area series is based on the line series, the QAreaSeries
constructor needs a QLineSeries
instance, which defines the upper boundary of the area. The area chart is drawn using the bottom of the plot area as the lower boundary by default. Instead of the bottom of the plot area, the lower boundary can be specified by another line. In that case, QAreaSeries
should be initialized with two QLineSeries
instances.
Note
The terms upper and lower boundary can be misleading in cases where the value of the lower boundary is greater than that of the upper boundary. The main point is that the area between these two boundary lines will be filled.
See the area chart example to learn how to create a simple area chart.
- class PySide6.QtCharts.QAreaSeries(upperSeries[, lowerSeries=None])#
PySide6.QtCharts.QAreaSeries([parent=None])
- Parameters:
upperSeries –
PySide6.QtCharts.QLineSeries
lowerSeries –
PySide6.QtCharts.QLineSeries
parent –
PySide6.QtCore.QObject
Constructs an area series object that will be spanned between an upperSeries
line and a lowerSeries
line. If no lowerSeries
is passed to the constructor, the x-axis is used as the lower bound instead.
The QAreaSeries
does not own the upper or lower series, but the ownership stays with the caller. When the series object is added to QChartView
or QChart
, the instance ownership is transferred.
Constructs an area series object without an upper or a lower series with the parent
object.
Note
Properties can be used directly when from __feature__ import true_property
is used or via accessor functions otherwise.

- property PᅟySide6.QtCharts.QAreaSeries.pointLabelsFormat: str#
This property holds The format used for showing labels with series points..
QAreaSeries
supports the following format tags:
@xPoint
The x value of the data point
@yPoint
The y value of the data point
For example, the following usage of the format tags would produce labels that have the data point (x, y) shown inside brackets separated by a comma:
series->setPointLabelsFormat("(@xPoint, @yPoint)");
By default, the label format is set to @xPoint, @yPoint
. The labels are shown on the plot area, whereas labels on the edge of the plot area are cut. If the points are close to each other, the labels may overlap.
