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.
