PlotAxes.pie(x, explode, *, labelpad=None, labeldistance=None, **kwargs)[source]

Plot a pie chart.

  • *args (y or x, y) – The data passed as positional or keyword arguments. Interpreted as follows:

    • If only y coordinates are passed, try to infer the x coordinates from the Series or DataFrame indices or the DataArray coordinates. Otherwise, the x coordinates are np.arange(0, y.shape[0]).

    • If the y coordinates are a 2D array, plot each column of data in succession (except where each column of data represents a statistical distribution, as with boxplot, violinplot, or when using means=True or medians=True).

    • If any arguments are pint.Quantity, auto-add the pint unit registry to matplotlib’s unit registry using setup_matplotlib. A pint.Quantity embedded in an xarray.DataArray is also supported.

  • data (dict-like, optional) – A dict-like dataset container (e.g., DataFrame or Dataset). If passed, each data argument can optionally be a string key and the arrays used for plotting are retrieved with data[key]. This is a native matplotlib feature.

  • autoformat (bool, optional) – Whether the x axis labels, y axis labels, axis formatters, axes titles, legend titles, and colorbar labels are automatically configured when a Series, DataFrame, DataArray, or Quantity is passed to the plotting command. Default is rc.autoformat = True. Formatting of pint.Quantity unit strings is controlled by rc.unitformat = 'L'.

Other Parameters
  • cycle (cycle-spec, optional) – The cycle specifer, passed to the Cycle constructor. If the returned cycler is unchanged from the current cycler, the axes cycler will not be reset to its first position. To disable property cycling and just use black for the default color, use cycle=False, cycle='none', or cycle=() (analogous to disabling ticks with e.g. xformatter='none'). To restore the default property cycler, use cycle=True.

  • cycle_kw (dict-like, optional) – Passed to Cycle.

  • lw, linewidth, linewidths (unit-spec, optional) – The edge width of the patch(es). Default is rc['patch.linewidth'] = 0.6. If float, units are points. If string, interpreted by units.

  • ls, linestyle, linestyles (str, optional) – The edge style of the patch(es). Default is '-'.

  • ec, edgecolor, edgecolors (color-spec, optional) – The edge color of the patch(es). Default is 'none'.

  • fc, facecolor, facecolors, fillcolor, fillcolors (color-spec, optional) – The face color of the patch(es). Default is to use the property cycle.

  • a, alpha, alphas (float, optional) – The opacity of the patch(es).

  • edgefix (bool or float, optional) – Whether to fix the common issue where white lines appear between adjacent patches in saved vector graphics (this can slow down figure rendering). See this stackoverflow post for a demonstration of the problem. Default is rc.edgefix = True. If True, a small default linewidth is used to cover up the white lines. If float (e.g. edgefix=0.5), this specific linewidth is used to cover up the white lines. This feature is automatically disabled when the patches have transparency.

  • label, value (float or str, optional) – The single legend label or colorbar coordinate to be used for this plotted element. Can be numeric or string. This is generally used with 1D positional arguments.

  • labels, values (sequence of float or sequence of str, optional) – The legend labels or colorbar coordinates used for each plotted element. Can be numeric or string, and must match the number of plotted elements. This is generally used with 2D positional arguments.

  • labelpad, labeldistance (float, optional) – The distance at which labels are drawn in radial coordinates.
