Sparklines
==========

pygal provides a simple way to get beautiful sparklines.


.. contents::


Basic
-----

.. pygal-code:: sparkline

  chart = pygal.Line()
  chart.add('', [1, 3,  5, 16, 13, 3,  7])
  chart.render_sparkline()


Styles
------

It supports styling like any chart but the option is given to the `render_sparkline` method:

.. pygal-code:: sparkline

  from pygal.style import DarkSolarizedStyle
  chart = pygal.Line()
  chart.add('', [1, 3,  5, 16, 13, 3,  7])
  chart.render_sparkline(style=DarkSolarizedStyle)


Options
-------

It's the same for other options:

.. pygal-code:: sparkline

  chart = pygal.Line()
  chart.add('', [1, 3,  5, 16, 13, 3,  7])
  chart.render_sparkline(interpolate='cubic')

.. pygal-code:: sparkline

  chart = pygal.Line()
  chart.add('', [1, 3,  5, 16, 13, 3,  7, 9, 2, 1, 4, 9, 12, 10, 12, 16, 14, 12, 7, 2])
  chart.render_sparkline(width=500, height=25, show_dots=True)


Sparktext
---------

If you want to get a simple spartext, use the render_sparktext function:

.. code-block:: python

  chart = pygal.Line()
  chart.add('', [1, 3,  5, 16, 13, 3,  7])
  chart.render_sparktext()

→ `▁▁▂█▆▁▃`

You can also specify an explicit minimum for the values:

.. code-block:: python

  chart = pygal.Line()
  chart.add('', [1, 3,  5, 16, 13, 3,  7])
  chart.render_sparktext(relative_to=0)

→ `▁▂▃█▆▂▄`
