Class DataViewDefinitionBuilder

Generatore di oggetti DataViewDefinition.

Ecco un esempio di utilizzo dello Strumento per la creazione di segmenti di pubblico. I dati vengono importati da un foglio di lavoro Google.

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.
  const 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.
  const originalChart = Charts.newTableChart()
                            .setDimensions(600, 500)
                            .setDataSourceUrl(dataSourceUrl)
                            .build();

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

  const htmlOutput = HtmlService.createHtmlOutput();
  const originalChartData = Utilities.base64Encode(
      originalChart.getAs('image/png').getBytes(),
  );
  const originalChartUrl =
      `data:image/png;base64,${encodeURI(originalChartData)}`;
  const limitedChartData = Utilities.base64Encode(
      limitedChart.getAs('image/png').getBytes(),
  );
  const limitedChartUrl =
      `data:image/png;base64,${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;
