Create chart

createChart() creates a chart from data. A chart with 2 lines is created by this method.

function createChart(){
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var chart = sheet.newChart()
    .setChartType(Charts.ChartType.COMBO)
    .addRange(sheet.getRange('a1:a18'))
    .addRange(sheet.getRange('b1:b18'))
    .addRange(sheet.getRange('c1:c18'))
    .setPosition(5, 5, 0, 0)
    .setOption('series', {
      0:{type: 'line', color: 'red', curveType: 'function'},
      1:{type: 'line', color: 'blue', curveType: 'function'},
    })
    .setOption('useFirstColumnAsDomain', true)
    .setOption('height', 280)
    .setOption('width', 480)
    .setOption('title', 'Sample chart')
    .setOption('vAxis', {
      minValue: 0,
      maxValue: 0.4,
      gridlines: {
        count: 10
      }
    })
    .build();
  sheet.insertChart(chart);
}

Created chart

note

  • .setChartType(Charts.ChartType.COMBO) defines COMBO chart.
  • .setOption('series', {}) defines each type for range 'b1:b18' and 'c1:c18'.
  • 0:{} and 1:{} of .setOption('series', {}) mean range 'b1:b18' and 'c1:c18', respectively.

Modify chart

modifyChart() modifies the chart with 2 lines. It modifies from red line to red bars.

function modifyChart(){
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var chart = sheet.getCharts()[0];
  chart = chart.modify()
    .setChartType(Charts.ChartType.COMBO)
    .addRange(sheet.getRange('a1:a18'))
    .addRange(sheet.getRange('b1:b18'))
    .addRange(sheet.getRange('c1:c18'))
    .setPosition(5, 5, 0, 0)
    .setOption('series', {
      0:{type: 'bars', color: 'red'},
      1:{type: 'line', color: 'blue', curveType: 'function'},
    })
    .setOption('useFirstColumnAsDomain', true)
    .setOption('height', 280)
    .setOption('width', 480)
    .setOption('title', 'Sample chart')
    .setOption('vAxis', {
      minValue: 0,
      maxValue: 0.4,
      gridlines: {
        count: 10
      }
    })
    .build();
  sheet.updateChart(chart);
}
