Description:

qcustomplotpyside2 2.1.5

Pyside2 bindings for QCustomplot
This project provides Python (v3.6 - v3.10) bindings for the popular OpenSource QCustomPlot (v2.1.0) Qt (v5.15.2) plotting library.
The bindings are provided for Linux and Windows (64bit).
The project can be found on Github.
Installation
You can install the library and run the examples with the following commands.
Preferably you should do this in a python virtual environment.
pip install qcustomplot_pyside2 # Install latest version of the library
qcustomplot_examples # Start demos with default delay
qcustomplot_examples 0 # Start demos without automatic continuation
qcustomplot_examples 5000 # Continue demos every 5000 ms

Examples
The folder qcustomplot_examples_pyside2 contains the examples from the QCustomplot C++ webpage translated to Python.
These can be used as basis for own development or for seeing the features of the library.
Running all examples
The example command qcustomplot_examples linking to the script all_demos.py runs through all examples
with a default or user specified delay time.

Install the matching python wheel from the wheels directory (preferably in a virtual environment).
Start the shell script 'qcustomplot_examples' which will run all examples

Simple example code
import shiboken2 as Shiboken
from PySide2 import QtGui
import sys
import math
from random import uniform,randint
from PySide2.QtWidgets import QApplication, QDialog, QLineEdit, QPushButton, QVBoxLayout,QWidget,QMainWindow
from PySide2.QtGui import QLinearGradient, QRadialGradient, QColor, QBrush, QPen, QFont, QPixmap, QPainterPath
from PySide2.QtCore import Qt, QMargins,QPointF,QObject,QCoreApplication,QFile,QTimer,QLocale,QDateTime,QDate,QSize,QTime
from PySide2.QtUiTools import QUiLoader
from qcustomplot_pyside2 import *

def demo(app):
# Create plot
customPlot = QCustomPlot()
customPlot.resize(800, 600)
customPlot.setWindowTitle('Quadratic Demo')

# generate some data:
x = [0.0] * 101 # initialize with entries 0..100
y = [0.0] * 101
for i in range(0, 101):
x[i] = i/50.0 - 1 # x goes from -1 to 1
y[i] = x[i]*x[i] # let's plot a quadratic function

# create graph and assign data to it:
customPlot.addGraph()
customPlot.graph(0).setData(x, y)
# give the axes some labels:
customPlot.xAxis.setLabel("x")
customPlot.yAxis.setLabel("y")
# set axes ranges, so we see all data:
customPlot.xAxis.setRange(-1, 1)
customPlot.yAxis.setRange(0, 1)

# show the plot
customPlot.show()
# run the main Qt loop
res = app.exec_()
# Make sure and manually reset pointer
customPlot = None
return res


if __name__ == '__main__':
# Create the Qt Application
app = QApplication(sys.argv)
res = demo(app)
sys.exit(res)

All screenshots can also be found in the figures directory.
Versions
The version naming of the Python bindings is analogue to the naming of the QCustomPlot library.

v2.0.1: QCustomPlot library 2.0.1: All basic features
v2.1.0: QCustomPlot library 2.1.0: Experimental radial plots and more bindings.
v2.1.1: Small bugfixes
v2.1.2: Small bugfixes for Scatterplot with single points
v2.1.4: Bugfix for zero line and issue #4
v2.1.5: Allow python access to all public fields of QCP (issue #5)
(Note: Access to QCP public fields has changed from methods, e.g. w.start() to fields, e.g. w.start, methods are available still as w.get_start())

License
This project is licensed under the GPLv3+ License - see the LICENSE file for details.
Additionally, you can also use these bindings / these python wheels in commercial projects:

if you have a commercial license for QCustomPlot 2.x
fullfill the Qt license requirements, which typically mean you are using only the LGPL features of Qt 5.x or have a commercial license of Qt 5.x (as the bindings link only dynamically to Qt)

Note that commercial licenses are available for [QCustomPlot] at https://www.qcustomplot.com/.
