plottr 0.9.3rc1

A tool for live plotting and processing data

plottr: modular data plotting and processing

A framework for inspecting data, based on flowcharts from pyqtgraph. plottr's main aim is to allow the user to define custom data processing flows and plotting. A particular use case is data filtering and plotting.

Documentation:

https://plottr.readthedocs.io (work in progress...)

Quickstart

Installation

Plottr is installable from pypi with pip install plottr

Plottr requires either the PyQt5 or Pyside2 gui framework. To install with PyQt5 or Pyside2 backend you can do pip install plottr[PyQt5] or pip install plottr[Pyside2]

Note that if you have installed pyqt from (Ana)Conda you should not use any of these targets but do pip install plottr or install Plottr from conda forge:

conda config --add channels conda-forge
conda config --set channel_priority strict
conda install plottr

To install from source: clone the repo, and install using pip install -e .

inspectr: QCoDeS dataset inspection and (live) plotting

You can use the inspectr tool to get a simple overview over QCoDeS database files, and plot datasets contained in the database.

To use: run plottr-inspectr [--dbpath <path to your .db file>]

As an alternative from the root of the cloned plottr repository, run python apps/inspectr.py [--dbpath <path to your .db file>]

For basic instructions, check out the Notebook Live plotting qcodes data under /doc/examples.

Some notes on installing

Note: this package is not compatible with the original plottr tool. You might want to install freshly if you still use the old version.

Requirements:

• python >= 3.7 (f-strings...)
• the usual: numpy, mpl, ...
• pandas >= 0.22
• xarray
• pyqtgraph >= 0.12.1
