Graph types supported:

• Bar Graphs
• Color charts
• Multi-variable
• Stacked charts
• Horizontal or Vertical
• Emoji!

Examples

termgraph.py data/ex1.dat

# Reading data from data/ex1.dat

An example using emoji as custom tick:

termgraph.py data/ex1.dat --custom-tick ":runner:" --width 20 --title "Running Data"

# Running Data

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

An example using stdin and emoji:

echo "Label,3,9,1" | termgraph.py --custom-tick ":grinning:" --no-title --no-label


:grinning::grinning::grinning: 3.00
:grinning::grinning::grinning::grinning::grinning::grinning::grinning::grinning::grinning: 9.00
:grinning: 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.py data/ex4.dat --color {blue,red} --no-title

termgraph.py data/ex7.dat --color {yellow,magenta} --stacked --title "Stacked Data"

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

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

Install

• Works best with python3
• pip3 install colorama
• Download script, set executable and put in path

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.py [datafile]

• Help: termgraph.py -h

usage: termgraph.py [-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]

positional arguments:
  filename              data file name (comma or space separated). Defaults to
                        stdin.

optional arguments:

  --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.

  --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.
