Previously missing values have object data type. (GH8045) Enhancements in the plotting functions: • Added layout keyword to DataFrame.plot. You can pass a tuple of (rows, columns), one of which can be -1 to automatically the DataFrame or Series called plot method. Data will be transposed to meet matplotlib’s default layout. – DataFrame or Series: Draw matplotlib.table using the passed data. The data will be drawn as displayed

cases, it’s very hard to predict whether it will return a view or a copy (it depends on the memory layout of the array, about which pandas makes no guarantees), and therefore whether the __setitem__ will base::merge.data.frame in R). The reason for this is careful algorithmic design and the internal layout of the data in DataFrame. See the cookbook for some advanced strategies. Users who are familiar General plot style arguments Most plotting methods have a set of keyword arguments that control the layout and formatting of the returned plot: In [113]: plt.figure(); In [114]: ts.plot(style='k--', label='Series');
