Interface DataViewDefinitionBuilder

Builder for DataViewDefinition objects.

Here's an example of using the builder. The data is imported from a Google spreadsheet.

function doGet() {
  // This example creates two table charts side by side. One uses a data view definition to
  // restrict the number of displayed columns.

  // Get sample data from a spreadsheet.
  var dataSourceUrl = 'https://docs.google.com/spreadsheet/tq?range=A1%3AF' +
      '&key=0Aq4s9w_HxMs7dHpfX05JdmVSb1FpT21sbXd4NVE3UEE&gid=4&headers=-1';

  // Create a chart to display all of the data.
  var originalChart = Charts.newTableChart()
      .setDimensions(600, 500)
      .setDataSourceUrl(dataSourceUrl)
      .build();

  // Create another chart to display a subset of the data (only columns 1 and 4).
  var dataViewDefinition = Charts.newDataViewDefinition().setColumns([0, 3]);
  var limitedChart = Charts.newTableChart()
      .setDimensions(200, 500)
      .setDataSourceUrl(dataSourceUrl)
      .setDataViewDefinition(dataViewDefinition)
      .build();

  var htmlOutput = HtmlService.createHtmlOutput();
  var originalChartData = Utilities.base64Encode(originalChart.getAs('image/png').getBytes());
  var originalChartUrl = "data:image/png;base64," + encodeURI(originalChartData);
  var limitedChartData = Utilities.base64Encode(limitedChart.getAs('image/png').getBytes());
  var limitedChartUrl = "data:image/png;base64," + encodeURI(limitedChartData);
  htmlOutput.append("<table><tr><td>");
  htmlOutput.append("<img border=\"1\" src=\"" + originalChartUrl + "\">");
  htmlOutput.append("</td><td>");
  htmlOutput.append("<img border=\"1\" src=\"" + limitedChartUrl + "\">");
  htmlOutput.append("</td></tr></table>");
  return htmlOutput;
}
