Plotter

This Qt Python application connects to an SQL database generated by Sentinel to provide real-time plotting of the collected data.

Installing

• Create a new virtual environment: virtualenv venv
• Activate it: source venv/bin/activate
• Install the dependencies: pip install -r requirements.txt

MacOS: install pscopg2

Make sure OpenSSL is install with Brew. Type export LDFLAGS="-L/usr/local/opt/openssl/lib", and then install pyscopg2 with pip or pipenv.

Usage

• Configure the URL of the database you want to use in the app_config.db_path variable (see here for more information).
• Run the app with python app.py

Performance analysis

To profile the app in order to try and improve its performance, you can use the scripts in the tools folder.

• tools/profiling.py runs app.py for 100 seconds and dumps the profile trace to a file called result
• analyze.py reads the result file and formats out its contents
