5ebed791db006075701c16b2e8eb9566207f2548,"ENH: Plotting support for interval coordinates: groupby_bins (#2152)

* ENH: Plotting for groupby_bins

DataArrays created with e.g. groupy_bins have coords containing of pd._libs.interval.Interval. For plotting, the pd._libs.interval.Interval is replaced with the interval's center point. '_center' is appended to teh label

* changed pd._libs.interval.Interval to pd.Interval

* Assign new variable with _interval_to_mid_points instead of mutating original variable.

Note that this changes the the type of  xplt from DataArray to np.array in the line function.

* '_center' added to label only for 1d plot

* added tests

* missing whitespace

* Simplified test

* simplified tests once more

* 1d plots now defaults to step plot

New bool keyword `interval_step_plot` to turn it off.

* non-uniform bin spacing for pcolormesh

* Added step plot function

* bugfix: linestyle == '' results in no line plotted

* Adapted to upstream changes

* Added _resolve_intervals_2dplot function, simplified code

* Added documentation

* typo in documentation

* Fixed bug introduced by upstream change

* Refactor out utility functions.

* Fix test.

* Add whats-new.

* Remove duplicate whats new entry. :/

* Make things neater.",2018-10-23T08:19:22Z,2018-10-23T08:19:22Z,fde3c03652523db098120c122b3273dbe85e9cd1,0c7e9e762dbfd6554e60c953bf27493047d95109,13221727,,2448579
