An example using emoji as custom tick:
termgraph.py 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.py --custom-tick "?" --no-title --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.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
