Hey all, Everyone should be aware of https://github.com/matplotlib/matplotlib/pull/4787 which is both a very simple, but very important change to the mpl API by providing a minimal API to pass labeled data (that is anything that `foo[key]` return an array-like object) into mpl plotting functions.
This is due to Fernando and Brian's persuasive case to the importance of starting to address labeled data in mpl and it is now or in 6-9 months The general approach follows R / seaborn / panadas and allows users to pass in a `data` kwarg which if present, any data fields which are strings are replaced by a call to `data[key]`. In code ax.plot(labeled_data['a'], labeled_data['b']) and ax.plot('a', 'b', data=labeled_data) are equivalent. This is the minimal change to get quality of life for users who work with labeled data at the repl and to put a flag in the sand for the API that down stream projects should be targeting. Major changes to what the plotting functions do (inferring labels, inferring what computation to do etc) are out of scope for _this_ PR which I want to see included in 1.5. What a higher-level API which can make use of the additional meta-data available looks like is a much larger discussion which will must have input from all of the stake holders (ex IPython, pandas, bokeh, seaborn, xray).
