How to accurately embed visual data charts in Python Pyside6

Pyside6 is a Python GUI development library based on the Qt framework. It provides rich UI components and functions and supports multiple operating systems.

Embedding charts in Pyside6 is a common need because charts can visually display data.

1. Install PyQtChart

PyQtChart is a Qt extension module that provides a variety of chart types, such as line charts, bar charts, pie charts, etc.

Using PyQtChart in Pyside6 requires installing it first. It can be installed through the following command:

pip install PyQt6-Chart

2. Import PyQtChart and PyQt6

Embedding charts in Pyside6 requires importing PyQtChart and PyQt6 libraries. It can be imported through the following code:

from PySide6.QtCharts import QtCharts
from PySide6.QtGui import QPainter
from PySide6.QtWidgets import QApplication, QMainWindow

3. Create windows and charts

First you need to create a window and a chart. It can be created by the following code:

app = QApplication([])
window = QMainWindow()
chart = QtCharts.QChart()

Here a QApplication object named app and a named window are created. QMainWindow object and a QChart object named chart.

4. Create a chart sequence

A chart sequence is an object used to display data in a chart. You can create multiple series, each showing a set of data.

You can create a sequence using the following code:

series = QtCharts.QLineSeries()
series.append(0, 6)
series.append(2, 4)
series.append(3, 8)
series.append(7, 4)
chart.addSeries(series)

Here a QLineSeries object named series is created and four are added to it data points. The series is then added to the chart.

5. Create a chart view

The chart view is an object used to display charts. Multiple views can be created, each showing the same chart. You can use the following code to create a view:

chartView = QtCharts.QChartView(chart)
chartView.setRenderHint(QPainter.Antialiasing)
window.setCentralWidget(chartView)
window.show()

Here a QChartView object named chartView is created and the chart object chart is set for its properties.

Then the rendering hint and the central part of the window are set to the view, and the window is displayed.

The complete code is as follows:

from PySide6.QtCharts import QtCharts
from PySide6.QtGui import QPainter
from PySide6.QtWidgets import QApplication, QMainWindow
app = QApplication([])
window = QMainWindow()
chart = QtCharts.QChart()
series = QtCharts.QLineSeries()
series.append(0, 6)
series.append(2, 4)
series.append(3, 8)
series.append(7, 4)
chart.addSeries(series)
chartView = QtCharts.QChartView(chart)
chartView.setRenderHint(QPainter.Antialiasing)
window.setCentralWidget(chartView)
window.show()
app.exec_()
