Draws Graphs in the Terminal with Python

If you are an advanced Linux or Mac user, you may use the terminal often.

Sometimes the terminal commands you run show a progress bar.

Like this:

Wondering how to show a progress bar in the terminal?

You can with termgraph

If you have a simple data file like this:

# Example Data Set 1
2007    183.32
2008    231.23
2009     16.43
2010     50.21
2011    508.97
2012    212.05
2014 1.0

Then you can plot it like this:

~  ~/.local/bin/termgraph data.txt

2007: β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡ 183.32
2008: β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡ 231.23

2010: β–‡β–‡β–‡β–‡ 50.21
2011: β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡β–‡ 508.97

From Python

Yes, you want to do this from code!

You can use this module from Python like this:

from termgraph import termgraph as tg

labels = ['2007', '2008', '2009', '2010', '2011', '2012', '2014']
data = [[183.32, 190.52], [231.23, 5.0], [16.43, 53.1], [50.21, 7.0], [508.97, 10.45], [212.05, 20.2], [30.0, 20.0]]
normal_data = [[48.059508408796894, 50.0], [60.971862871927556, 0.0],
               [3.080530401034929, 12.963561880120743],
               [12.184670116429496, 0.5390254420008624],
               [135.82632600258734, 1.4688443294523499],
               [55.802608883139285, 4.096593359206555],
               [6.737818025010781, 4.042690815006468]]
len_categories = 2
args = {'filename': 'data/ex4.dat', 'title': None, 'width': 50,
        'format': '{:<5.2f}', 'suffix': '', 'no_labels': True,
        'color': None, 'vertical': False, 'stacked': True,
        'different_scale': False, 'calendar': False,
        'start_dt': None, 'custom_tick': '', 'delim': '',
        'verbose': False, 'version': False}
colors = [91, 94]
tg.stacked_graph(labels, data, normal_data, len_categories, args, colors)

What's the difference between the normal data and data? I'm not following how the data file and program inputs match. Would be grateful for more info!
