# matplotlib.axes.Axes.pie¶

`Axes.``pie`(x, explode=None, labels=None, colors=None, autopct=None, pctdistance=0.6, shadow=False, labeldistance=1.1, startangle=None, radius=None, counterclock=True, wedgeprops=None, textprops=None, center=(0, 0), frame=False)

Plot a pie chart.

Make a pie chart of array x. The fractional area of each wedge is given by x/sum(x). If sum(x) <= 1, then the values of x give the fractional area directly and the array will not be normalized. The wedges are plotted counterclockwise, by default starting from the x-axis.

Keyword arguments:

explode: [ None | len(x) sequence ]
If not None, is a `len(x)` array which specifies the fraction of the radius with which to offset each wedge.
colors: [ None | color sequence ]
A sequence of matplotlib color args through which the pie chart will cycle. If `None`, will use the colors in the currently active cycle.
labels: [ None | len(x) sequence of strings ]
A sequence of strings providing the labels for each wedge
autopct: [ None | format string | format function ]
If not None, is a string or function used to label the wedges with their numeric value. The label will be placed inside the wedge. If it is a format string, the label will be `fmt%pct`. If it is a function, it will be called.
pctdistance: scalar
The ratio between the center of each pie slice and the start of the text generated by autopct. Ignored if autopct is None; default is 0.6.
labeldistance: scalar
The radial distance at which the pie labels are drawn
shadow: [ False | True ]
Draw a shadow beneath the pie.
startangle: [ None | Offset angle ]
If not None, rotates the start of the pie chart by angle degrees counterclockwise from the x-axis.

radius: [ None | scalar ] The radius of the pie, if radius is None it will be set to 1.

counterclock: [ False | True ]
Specify fractions direction, clockwise or counterclockwise.
wedgeprops: [ None | dict of key value pairs ]
Dict of arguments passed to the wedge objects making the pie. For example, you can pass in wedgeprops = { ‘linewidth’ : 3 } to set the width of the wedge border lines equal to 3. For more details, look at the doc/arguments of the wedge object. By default `clip_on=False`.
textprops: [ None | dict of key value pairs ]
Dict of arguments to pass to the text objects.

center: [ (0,0) | sequence of 2 scalars ] Center position of the chart.

frame: [ False | True ]
Plot axes frame with the chart.

The pie chart will probably look best if the figure and axes are square, or the Axes aspect is equal. e.g.:

```figure(figsize=(8,8))
ax = axes([0.1, 0.1, 0.8, 0.8])
```

or:

```axes(aspect=1)
```
Return value:

If autopct is None, return the tuple (patches, texts):

If autopct is not None, return the tuple (patches, texts, autotexts), where patches and texts are as above, and autotexts is a list of `Text` instances for the numeric labels.

Note

In addition to the above described arguments, this function can take a data keyword argument. If such a data argument is given, the following arguments are replaced by data[<arg>]:

• All arguments with the following names: ‘colors’, ‘explode’, ‘labels’, ‘x’.
