Project description

Termgraph

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
  • Emoji!

Examples

termgraph data/ex1.dat

# Reading data from data/ex1.dat

2007: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 183.32
2008: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 231.23
2009: ▇ 16.43
2010: ▇▇▇▇ 50.21
2011: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 508.97
2012: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 212.05
2014: ▏ 1.00

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}
Multi variable bar chart with colors
termgraph data/ex7.dat --color {yellow,magenta} --stacked --title "Stacked Data"
Multi variable stacked bar chart with colors

Calendar Heatmap, expects first column to be date in yyyy-mm-dd

termgraph --calendar --start-dt 2017-07-01 data/cal.dat
Calendar Heatmap

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.
