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:
from PyQt5.QtGui import QPen, QBrush, QColor from QCustomPlot2 import * customPlot = QCustomPlot() 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.setInteractions(QCPInteractions(QCP.iRangeDrag | QCP.iRangeZoom | QCP.iSelectPlottable))
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.

If you have questions regarding the library, I would like to invite you to open an issue at OSDN. Please describe your request, problem, or question as detailed as possible, and also mention the version of the library you are using as well as the version of your compiler and operating system. Opening an issue at GitHub allows other users and contributors to this library to collaborate.
I deeply appreciate the help of the following people.
Thanks a lot for helping out! Please let me know if I forgot someone.
This library is built, tested, documented, and whatnot using third-party tools and services. Thanks a lot!
If you are using QCustomPlot2-PyQt5 in a project and would like to share with the community, please let me know, or even better, raise a pull request.
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/cjgdev/QCustomPlot2-PyQt5.git && cd QCustomPlot2-PyQt5 # Build $ CFLAGS=-std=c++11 CXXFLAGS=-std=c++11 python setup.py build # Zzz.. # Install $ python setup.py 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 python setup.py build # Zzz.. # Install python setup.py 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/cjgdev/QCustomPlot2-PyQt5.git && cd QCustomPlot2-PyQt5 # Build $ CFLAGS='-std=c++11 -stdlib=libc++' CXXFLAGS='-std=c++11 -stdlib=libc++' python3 setup.py build # Zzz.. # Install $ python3 setup.py install
If you need to override the paths for any reason, the way to do that is by modifying setup.cfg to match your environment. You will need to add a section as below, substituting everything between
>> with the correct paths.
[build_ext] qmake = <<PATH_TO>>\qmake.exe qt-include-dir = <<QT_INCLUDE_DIR>>\include qt-library-dir = <<QT_LIBRARY_DIR>>\lib make = <<PATH_TO>>\jom.exe
