socket-plotter 0.1.3

A simple live plotter via socket.

socket-plotter

Instant plotter based on pyqtgraph via socket communication.

Installation

1. (if you want) create a python environment
2. install PySide2 manually
   • pip install PySide2 or conda install -c conda-forge pyside2
3. pip install socket-plotter

dependency

• PySide2
• pyqtgraph

Usage

from socket_plotter import plot_lines, plot_image, plot_image_and_lines
import numpy as np

# for line plot
xdata = np.arange(100)
ydata = np.random.randn(100)
plot_lines(xdata, ydata)

# for image plot
img = np.random.randn(100, 100)
plot_image(img)

# for both, the image and each row of the image are displayed.
img = np.random.randn(100, 100)
plot_image_and_lines(img)

The above three functions check if a plotter process exists. If needed, a new plotter process will be launched before plotting.

address and ports

The default ports are 8765 for lineplot and 8766 for imageplot. The default address is 127.0.0.1. Other ports and address can be assigned as the following:

plot_lines(xdata, ydata, addr='<address to plotter>', port=7777)

python environment

You can specify your python executable to launch plotter GUIs via an environment variable SOCKETPLOTTER_PYTHON_EXECUTABLE
