Class PieChartBuilder

A builder for pie charts. For more details, see the Google Charts documentation.

Here is an example that shows how to build a pie chart. The data is imported from a Google spreadsheet.

  // Get sample data from a spreadsheet.
  var dataSourceUrl = 'https://docs.google.com/spreadsheet/tq?range=A1%3AB8' +
      '&key=0Aq4s9w_HxMs7dHpfX05JdmVSb1FpT21sbXd4NVE3UEE&gid=3&headers=-1';

  var chartBuilder = Charts.newPieChart()
      .setTitle('World Population by Continent')
      .setDimensions(600, 500)
      .set3D()
      .setDataSourceUrl(dataSourceUrl);

  var chart = chartBuilder.build();

Detailed documentation

`build()`

Builds the chart.

Return

Chart — A Chart object, which can be embedded into documents, UI elements, or used as a static image.

`reverseCategories()`

Reverses the drawing of series in the domain axis. For vertical-range charts (such as line, area or column charts), this means the horizontal axis is drawn from right to left. For horizontal-range charts (such as bar charts), this means the vertical axis is drawn from top to bottom. For pie charts, this means the slices are drawn counterclockwise.

// Creates a pie chart builder and sets drawing of the slices in a counter-clockwise manner.
var builder = Charts.newPieChart();
builder.reverseCategories();

Return

PieChartBuilder — This builder, useful for chaining.

`set3D()`

Sets the chart to be three-dimensional.

Return

PieChartBuilder — This builder, useful for chaining.

`setBackgroundColor(cssValue)`

Sets the background color for the chart.

// Creates a line chart builder and sets the background color to gray
var builder = Charts.newLineChart();
builder.setBackgroundColor("gray");

Parameters

Name	Type	Description
`cssValue`	`String`	The CSS value for the color (such as `"blue"` or `"#00f"`).

Return

PieChartBuilder — This builder, useful for chaining.

`setColors(cssValues)`

Sets the colors for the lines in the chart.

// Creates a line chart builder and sets the first two lines to be drawn in green and red,
// respectively.
var builder = Charts.newLineChart();
builder.setColors(["green", "red"]);

Parameters

Name	Type	Description
`cssValues`	`String[]`	An array of color CSS values, such as `["red", "#acf"]`. The nth element in the array represents the color of the nth line in the chart.

Return

PieChartBuilder — This builder, useful for chaining.

`setDataSourceUrl(url)`

Sets the data source URL that is used to pull data in from an external source, such as Google Sheets. If a data source URL and a DataTable are provided, the data source URL is ignored.

For more information about querying data sources, check out the Google Charts documentation.
