Installation
To install PlainChart, you can use pipenv or pip:
$ pipenv install plainchart
Features
With PlainChart, you can:
render an array of values in a plain text chart
limit the height of the chart and have the values rendered accordingly
render a different style of chart, e.g., plainchart.PlainChart.bar or plainchart.PlainChart.scatter
implement your own style of chart, e.g., mean_html (see example below)
Examples
>>> import plainchart
>>> import random
>>>
>>> values = [random.randint(0, 10) for _ in range(100)]
>>> chart = plainchart.PlainChart(values)
>>>
>>> print(chart.render())

>>> import plainchart
>>> import math
>>> import numpy as np
>>>
>>> values = [1.3 + math.sin(x) for x in np.linspace(0, 4 * math.pi, num=100)]
>>> chart = plainchart.PlainChart(values, style=plainchart.PlainChart.scatter)

You can also implement your own style of chart. Below is an example of a HTML chart (mean_html.py) with different colors for values below and above the mean.
import plainchart
import random
import statistics
def mean_html(chart, value, y):
mean = statistics.mean(chart.values)
mean_y = chart.y(mean)
value_y = chart.y(value)
if value_y <= mean_y:
if y <= value_y:
return '<span style="color:green">▌</span>'
return '<span style="color:white">▌</span>'
else:
if y <= mean_y:
return '<span style="color:green">▌</span>'
elif y <= value_y:
return '<span style="color:red">▌</span>'
return '<span style="color:white">▌</span>'
values = [random.randint(0, 10) for _ in range(100)]
chart = plainchart.PlainChart(values, style=mean_html)
print(chart.render(new_line='<br>'))
$ python mean_html.py > mean.html
