This is Python bindings for QCustomPlot - Qt C++ library for plotting and data visualization. There are myriads of Python charting libraries out there, and each may even have its reason to exist. QCustomPlot2 for PyQt5 has the following goals:
Performance. QCustomPlot is written in modern C++ with the excellent Qt library for superior performance over alternative libraries.
Flexibility. QCustomPlot is one of the most customisable libraries available, with a wide range of supported graph types and full control over how the graph is rendered.
You can find compiled packages for many Linux distributions at OBS.
Install the package via our favourite package manager:
$ pip install QCustomPlot2
Now let's take a look at some code:
import sys
import math
from PyQt5.QtCore import Qt
from PyQt5.QtGui import QPen, QBrush, QColor
from PyQt5.QtWidgets import QApplication, QMainWindow
from QCustomPlot2 import *
app = QApplication(sys.argv)
window = QMainWindow()
window.resize(800, 600)
customPlot = QCustomPlot()
window.setCentralWidget(customPlot)
graph0 = customPlot.addGraph()
graph0.setPen(QPen(Qt.blue))
graph0.setBrush(QBrush(QColor(0, 0, 255, 20)))
graph1 = customPlot.addGraph()
graph1.setPen(QPen(Qt.red))
x, y0, y1 = [], [], []
for i in range (251):
x.append(i)
y0.append(math.exp(-i/150.0)*math.cos(i/10.0)) # exponentially decaying cosine
y1.append(math.exp(-i/150.0)) # exponential envelope
graph0.setData(x, y0)
graph1.setData(x, y1)
customPlot.rescaleAxes()
customPlot.setInteraction(QCP.iRangeDrag)
customPlot.setInteraction(QCP.iRangeZoom)
customPlot.setInteraction(QCP.iSelectPlottables)
window.show()
sys.exit(app.exec_())
That's all!
Some important things:
Beside the examples below, you may want to check the documentation.
The following compilers are known to work:
I would be happy to learn about other compilers/versions.

Apt users (Debian, Ubuntu, etc) may follow the instructions below, users of other distributions may adapt the steps below for your own package manager.
# Fetch the necessary development tools and libraries
$ apt-get install build-essential python3-pyqt5 pyqt5-dev-tools qttools5-dev-tools
# Clone the repository and submodules
$ git clone --recursive https://github.com/salsergey/QCustomPlot2-PyQt5.git && cd QCustomPlot2-PyQt5
# Build
$ sip-build
# Zzz..
# Install
$ sip-install
Windows users should install Qt tools, appropriate version of VC compiler, Python, PyQt5 and SIP. You may need to build SIP from sources to ensure you have all files necessary for building other software. Then follow the instructions below to build the library, otherwise you will need to adapt the steps for your own environment.
# Go to QCustomPlot2 folder
cd <<PATH_TO QCustomPlot2-PyQt5>>
# Download submodules if you use git
git submodules update --init
# Build
sip-build
# Zzz..
# Install
sip-install
Users of macOS using homebrew may follow the instructions below to fetch the required packages to build the library, or simply adapt to your own environment.
# First ensure Xcode is installed, as homebrew depends on it
$ xcode-select --install
# Fetch the necessary development tools and libraries
$ brew install qt --devel sip --without-python@2 pyqt --without-python@2
# Clone the repository and submodules
$ git clone --recursive https://github.com/salsergey/QCustomPlot2-PyQt5.git && cd QCustomPlot2-PyQt5
# Build
$ CFLAGS='-std=c++11 -stdlib=libc++' CXXFLAGS='-std=c++11 -stdlib=libc++' sip-build
# Zzz..
# Install
$ sip-install
