pandas.Series.plot.box¶

Series.plot.
box
(self, by=None, **kwargs)[source]¶ Make a box plot of the DataFrame columns.
A box plot is a method for graphically depicting groups of numerical data through their quartiles. The box extends from the Q1 to Q3 quartile values of the data, with a line at the median (Q2). The whiskers extend from the edges of box to show the range of the data. The position of the whiskers is set by default to 1.5*IQR (IQR = Q3  Q1) from the edges of the box. Outlier points are those past the end of the whiskers.
For further details see Wikipedia’s entry for boxplot.
A consideration when using this chart is that the box and the whiskers can overlap, which is very common when plotting small sets of data.
