A python command-line tool which draws basic graphs in the terminal.
Graph types supported:
- Bar Graphs
- Color charts
- Multi-variable
- Stacked charts
- Horizontal or Vertical

Examples
termgraph data/ex1.dat
# Reading data from data/ex1.dat

An example using emoji as custom tick:
termgraph data/ex1.dat --custom-tick "🏃" --width 20 --title "Running Data"
# Running Data
2007: 🏃🏃🏃🏃🏃🏃🏃 183.32
2008: 🏃🏃🏃🏃🏃🏃🏃🏃🏃 231.23
2009: 16.43
2010: 🏃 50.21
2011: 🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃 508.97
2012: 🏃🏃🏃🏃🏃🏃🏃🏃 212.05
2014: 1.00
An example using stdin and emoji:
echo "Label,3,9,1" | termgraph --custom-tick "😀" --no-label
😀😀😀 3.00
😀😀😀😀😀😀😀😀😀 9.00
😀 1.00
Most results can be copied and pasted wherever you like, since they use standard block characters. However the color charts will not show, since they use terminal escape codes for color. A couple images to show color examples:
termgraph data/ex4.dat --color {blue,red}
termgraph data/ex7.dat --color {yellow,magenta} --stacked --title "Stacked Data"
Calendar Heatmap, expects first column to be date in yyyy-mm-dd
termgraph --calendar --start-dt 2017-07-01 data/cal.dat
Install
Works best with Python3, you can install from PyPI project
pip3 install termgraph
Note: Be sure your PATH includes the pypi install directory, for me it is ~/.local/bin/
Usage
-
Create data file with two columns either comma or space separated. The first column is your labels, the second column is a numeric data
-
termgraph [datafile]
-
Help: termgraph -h
usage: termgraph [-h] [--title TITLE] [--width WIDTH] [--format FORMAT]
[--suffix SUFFIX] [--no-labels]
[--color [{red,blue,green,magenta,yellow,black,cyan} [{red,blue,green,magenta,yellow,black,cyan} ...]]]
[--vertical] [--stacked] [--different-scale] [--calendar]
[--start-dt START_DT] [--custom-tick CUSTOM_TICK]
[--delim DELIM] [--verbose]
[filename]
draw basic graphs on terminal
positional arguments:
filename data file name (comma or space separated). Defaults to
stdin.
optional arguments:
-h, --help show this help message and exit
--title TITLE Title of graph
--width WIDTH width of graph in characters default:50
--format FORMAT format specifier to use.
--suffix SUFFIX string to add as a suffix to all data points.
--no-labels Do not print the label column
--color [{red,blue,green,magenta,yellow,black,cyan} [{red,blue,green,magenta,yellow,black,cyan} ...]]
Graph bar color( s )
--vertical Vertical graph
--stacked Stacked bar graph
--different-scale Categories have different scales.
--calendar Calendar Heatmap chart
--start-dt START_DT Start date for Calendar chart
--custom-tick CUSTOM_TICK
Custom tick mark, emoji approved
--delim DELIM Custom delimiter, default , or space
--verbose Verbose output, helpful for debugging
Background
I wanted a quick way to visualize data stored in a simple text file. I initially created some scripts in R that generated graphs but this was a two step process of creating the graph and then opening the generated graph.
After seeing command-line sparklines I figured I could do the same thing using block characters for bar charts.
