Live data visualisation via Matplotlib

polt is a Python package for live data visualisation via Matplotlib.

What can polt do?

Reading Numbers from STDIN

for i in `seq 1 100`;do echo $i;sleep $i;done | python3 -m polt

Reading CSV from STDIN

echo "a,b,c\n1,2,3\n3,4,5\n7,5,8\n" | while read line;do echo $line;sleep 1;done | python3 -m polt --source CsvParser:-

Further Possibilities

It is possible to split the data into subplots for

• quantity
• unit
• parser

See the help page python3 -m polt -h for further configuration options.

Configuration Files

polt can use configuration files (by default ~/.config/polt/polt.conf and .polt.conf in the current directory) to simplify invocation. It is also possible to save the current configuration with the --save-config option.

Custom Data Parsers

It is easy to add custom data parsers. See the help page python3 -m polt -h for more details.

Why on Earth is it called polt and not plot!?

I am a big fan of swapping syllables or characters around resulting in ridiculously-sounding words. polt is one of those words which I am generating quite frequently when typing quickly.
