ttyplot
Real-time terminal plotting from stdin
TLDR
Plot values from stdin
$ echo "1 2 3" | ttyplot
Set title and unit$ echo "1 2 3" | ttyplot -t "Title" -u "ms"
Continuously plot random values$ while true; do echo $RANDOM; sleep 1; done | ttyplot
Plot ping latency$ ping 8.8.8.8 | sed -u 's/^.*time=//g; s/ ms//g' | ttyplot -t "Ping" -u ms
Plot with two values (dual plot)$ command | ttyplot -2
SYNOPSIS
ttyplot [options]
DESCRIPTION
ttyplot is a real-time terminal plotting utility that reads numeric values from stdin and displays them as a scrolling graph in the terminal. It is useful for visualizing streaming data like network latency, CPU usage, or sensor readings.
PARAMETERS
-t TITLE
Set the plot title-u UNIT
Set the unit label for values-s SCALE
Set the vertical scale (max value)-m MIN
Set the minimum value-2
Enable dual/two value plotting mode-c COLOR
Set the plot color-e
Exit when stdin closes-r
Rate mode (values per second)
CAVEATS
Input must be numeric values, one per line. Use sed or awk to extract numeric values from command output. The plot resizes automatically with terminal size changes.
HISTORY
ttyplot was created as a simple way to visualize streaming numeric data directly in the terminal without requiring a graphical environment.
