Changelog
=========

2.3.1
=====

_This is a micro release and I have very little time on my hands right now sorry_

* Fix crash with no values when the print_values_position param is set (thanks @cristen)


2.3.0
=====

* New call API: `chart = Line(fill=True); chart.add('title', [1, 3, 12]); chart.render()` can now be replaced with `Line(fill=True)(1, 3, 12, title='title').render()`
* Drop python 2.6 support


2.2.3
=====

* Fix bar static value positioning (#315)

=====

* Support interruptions in line charts (thanks @piotrmaslanka #300)
* Fix confidence interval reactiveness (thanks @chartique #296)
* Add horizontal line charts (thanks @chartique #301)
* There is now a `formatter` config option to format values as specified. The formatter callable may or may not take `chart`, `serie` and `index` as argument.
