Example

$ python termgraph.py ex1.dat

Background

I wanted a quick way to visualize some data which is stored in a simple text file. I initiall created some scripts in R which generated graphs but tended to be a two step process of creating the graph and then opening the generated graph.

I did some graphing using gnuplot, but X11 would never be started so it took time to start. So after seeing command-line sparklines I figured I could do the same thing using block characters for bar charts.

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

• python termgraph.py [datafile]

TODO

I may or may not ever get around to these TODOs but a few ideas to take it further

• Add switch for vertical bar charts
• Add options and flags for width
• Add options for different colors
• Stacked Bar Charts
• Multiple series (side-by-side)

Release Info

• Ver 0.2 - Sep 22, 2012

  • Add width parameter

• Ver 0.1 - Sep 21, 2012 - Initial Horizontal Graphs
