Pie Chart

Draw a pie chart.

Examples

1. Basic pie chart.

::

let array_x = [1.0, 3.0, 0.5, 2.5, 2.0]
let x = vector<Float64>(array_x)
pie(x)

Result:

.. image:: ../../../tests/imgs/pie/pie_1.png :align: center :width: 360

2. Pie chart with custom explode.

::

let array_x = [1.0, 3.0, 0.5, 2.5, 2.0]
let x = vector<Float64>(array_x)
let array_ex = [0.0, 1.0, 0.0, 1.0, 0.0]
let ex = vector<Float64>(array_ex)
pie(x, ex)

Result:

.. image:: ../../../tests/imgs/pie/pie_2.png :align: center :width: 360

3. Pie chart with custom labels.

::

let array_x = [1.0, 2.0, 3.0]
let x = vector<Float64>(array_x)
let labels = ["Taxes", "Expenses", "Profit"]
pie(x, labels)

Result:

.. image:: ../../../tests/imgs/pie/pie_3.png :align: center :width: 360

4. Pie chart with a gap.

::

let array_x = [0.19, 0.22, 0.41]
let x = vector<Float64>(array_x)
pie(x)

Result:

.. image:: ../../../tests/imgs/pie/pie_4.png :align: center :width: 360

5. Two pie charts with different titles.

::

let array_2010 = [50.0, 0.0, 100.0, 95.0]
let array_2011 = [65.0, 22.0, 97.0, 120.0]

let y2010 = vector<Float64>(array_2010)
let y2011 = vector<Float64>(array_2011)

tiledlayout(2,1)
let ax1 = nexttile()
pie(y2010)
title("2010")

let ax2 = nexttile()
pie(y2011)
title("2011")

Result:

.. image:: ../../../tests/imgs/pie/pie_5.png :align: center :width: 360

6. Pie chart with custom explode and labels.

::

let array_x = [17.0, 33.0, 33.0, 17.0]
let array_ex = [0.0, 1.0, 1.0, 0.0]

let x = vector<Float64>(array_x)
let ex = vector<Float64>(array_ex)
let labels = ["East(17%)", "North(33%)", "South(33%)", "West(17%)"]

pie(x, ex, labels)

Result:

.. image:: ../../../tests/imgs/pie/pie_6.png :align: center :width: 360
