📋 👎🏿 🌁 pipeplot - interactive visualization of the data stream from pipe in the console 🧓🏿 ⛑️ ☃️

For those who do not want to leave the console, they love its ascii-graphics, a utility for drawing graphs from pipe has appeared. Under cat animation and examples.

Buffering

Many console utilities buffer stdout. Because of this, the serial pipe breaks. Some utilities support buffering: sed -u , grep --line-buffered . Otherwise, you can use the universal method stdbuf -oL and unbuffer .

Available options

the COLOR --color - the color of the columns, the number of palettes use Xterm
--symbol the SYMBOL - symbol to display columns support the seals
--scale all {,} window - setting automatic scaling minimum and maximum, all - takes into account all data, window - only the visible
--direction {left, right} - direction
--min MIN --max MAX - fixes the minimum and maximum, combined with automatic scaling

Installation

pip install pipeplot
