Scatter Chart

Scatter charts are used to show trends in data. They are especially useful when you have a large number of data points. Like line charts, they can be used to plot data recorded from scientific experiments, such as how a chemical reacts to changing temperature or atmospheric pressure.

Here is an example of Scatter Chart which takes data from spreadsheet to build the chart.

Here is the is the spreadsheet preview which serves as the data source for the chart.

Example Code:

function doGet(){

  //Get the data from spreadsheet

  ssID ='SpreadsheetID'//Change it to yours

  var SS = SpreadsheetApp.openById('ssID');

  var sheet = SS.getSheets()[0];

var data = sheet.getRange('A1:B10').getValues();

  //Build data table

  var dataTable = Charts.newDataTable();

  dataTable.addColumn(Charts.ColumnType.NUMBER, data[0][0]);

  dataTable.addColumn(Charts.ColumnType.NUMBER, data[0][1]);

  //Add rows

  for(var j=1; j<data.length; j++){

    dataTable.addRow(data[j]);

  }

  //Create and build chart

  var chart = Charts.newScatterChart()

      .setDataTable(dataTable)

      .setXAxisTitle('Particulate')

      .setYAxisTitle('Rainfall')

      .setYAxisRange(0, 140)

      .setTitle("Particulate levels in Rainfall")

      .build();

  var app = UiApp.createApplication().setTitle("AST Chart");

  app.add(chart)

  return app;
