        "\n# Separate calculation and plotting of boxplots\n\nDrawing a `~.axes.Axes.boxplot` for a given data set, consists of two main operations,\nthat can also be used separately:\n\n1. Calculating the boxplot statistics: `matplotlib.cbook.boxplot_stats`\n2. Drawing the boxplot: `matplotlib.axes.Axes.bxp`\n\nThus, ``ax.boxplot(data)`` is equivalent to ::\n\n    stats = cbook.boxplot_stats(data)\n    ax.bxp(stats)\n\nAll styling keyword arguments are identical between `~.axes.Axes.boxplot` and\n`~.axes.Axes.bxp`, and they are passed through from `~.axes.Axes.boxplot` to\n`~.axes.Axes.bxp`. However, the *tick_labels* parameter of `~.axes.Axes.boxplot`\ntranslates to a generic *labels* parameter in `.boxplot_stats`, because the labels are\ndata-related and attached to the returned per-dataset dictionaries.\n\nThe following code demonstrates the equivalence between the two methods.\n"
