Class EmbeddedChart

Represents a chart that has been embedded into a spreadsheet.

This example shows how to modify an existing chart:

var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getRange("A2:B8")
var chart = sheet.getCharts()[0];
chart = chart.modify()
    .addRange(range)
    .setOption('title', 'Updated!')
    .setOption('animation.duration', 500)
    .setPosition(2,2,0,0)
    .build();
sheet.updateChart(chart);

This example shows how to create a new chart:

function newChart(range, sheet) {
  var sheet = SpreadsheetApp.getActiveSheet();
  var chartBuilder = sheet.newChart();
  chartBuilder.addRange(range)
      .setChartType(Charts.ChartType.LINE)
      .setOption('title', 'My Line Chart!');
  sheet.insertChart(chartBuilder.build());
}

Detailed documentation

`getAs(contentType)`

Return the data inside this object as a blob converted to the specified content type. This method adds the appropriate extension to the filename—for example, "myfile.pdf". However, it assumes that the part of the filename that follows the last period (if any) is an existing extension that should be replaced. Consequently, "ShoppingList.12.25.2014" becomes "ShoppingList.12.25.pdf".

Parameters

Name	Type	Description
`contentType`	`String`	The MIME type to convert to. For most blobs, `'application/pdf'` is the only valid option. For images in BMP, GIF, JPEG, or PNG format, any of `'image/bmp'`, `'image/gif'`, `'image/jpeg'`, or `'image/png'` are also valid.

Return

Blob — The data as a blob.

`getBlob()`

Return the data inside this object as a blob.

Return

Blob — The data as a blob.

`getChartId()`

Returns a stable identifier for the chart that is unique across the spreadsheet containing the chart or null if the chart is not in a spreadsheet.

Return

Integer — A stable chart identifier.

`getContainerInfo()`

Returns information about where the chart is positioned within a sheet.

var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];

var chart = sheet.newChart()
    .setChartType(Charts.ChartType.BAR)
    .addRange(sheet.getRange("A1:B8"))
    .setPosition(5, 5, 0, 0)
    .build();

var containerInfo = chart.getContainerInfo();

// Logs the values we used in setPosition()
Logger.log("Anchor Column: %s\r\nAnchor Row %s\r\nOffset X %s\r\nOffset Y %s",
          containerInfo.getAnchorColumn(),
          containerInfo.getAnchorRow(),
          containerInfo.getOffsetX(),
          containerInfo.getOffsetY());

Return

ContainerInfo — an object containing the chart container's position

`getHiddenDimensionStrategy()`

Returns the strategy to use for handling hidden rows and columns. Defaults to IGNORE_ROWS.

var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];

var range = sheet.getRange("A1:B5");
var chart = sheet.newChart()
    .setChartType(Charts.ChartType.BAR)
    .addRange(range)
    .setHiddenDimensionStrategy(Charts.ChartHiddenDimensionStrategy.IGNORE_COLUMNS)
    .setPosition(5, 5, 0, 0)
    .build()

// Logs the strategy to use for hidden rows and columns which is
// Charts.ChartHiddenDimensionStrategy.IGNORE_COLUMNS in this case.
Logger.log(chart.getHiddenDimensionStrategy());

Return

ChartHiddenDimensionStrategy — The strategy to use for hidden rows and columns.

`getMergeStrategy()`

Returns the merge strategy used when more than one range exists. If MERGE_ROWS, row are merged; if MERGE_COLUMNS, columns are merged. Defaults to MERGE_COLUMNS.

var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];

var range = sheet.getRange("A1:B10");
var range2 = sheet.getRange("C1:C10");
var chart = sheet.newChart()
    .setChartType(Charts.ChartType.BAR)
    .addRange(range)
    .addRange(range2)
    .setMergeStrategy(Charts.ChartMergeStrategy.MERGE_ROWS)
    .setPosition(5, 5, 0, 0)
    .build()

// Logs whether rows of multiple ranges are merged, which is MERGE_ROWS in this case.
Logger.log(chart.getMergeStrategy());

Return

ChartMergeStrategy — MERGE_ROWS if rows are merged across multiple ranges; MERGE_COLUMNS if columns are merged across multiple ranges

`getNumHeaders()`

Returns the number of rows or columns the range that are treated as headers.

var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];

var range = sheet.getRange("A1:B5");
var chart = sheet.newChart()
    .setChartType(Charts.ChartType.BAR)
    .addRange(range)
    .setNumHeaders(1)
    .setPosition(5, 5, 0, 0)
    .build()

// Logs the number of rows or columns to use as headers, which is 1 in this case.
Logger.log(chart.getHeaders());

Return

Integer — The number of rows or columns treated as headers. Negative values indicate the headers are auto-detected.

`getOptions()`

Returns the options for this chart, such as height, colors, and axes.

The returned options are immutable.

Return

ChartOptions — The options for this chart, such as height, colors, and axes.

`getRanges()`

Returns the ranges that this chart uses as a data source.

var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];

var chart = sheet.newChart()
    .setChartType(Charts.ChartType.BAR)
    .addRange(sheet.getRange("A1:B8"))
    .setPosition(5, 5, 0, 0)
    .build();

var ranges = chart.getRanges();

// There's only one range as a data source for this chart,
// so this logs "A1:B8"
for (var i in ranges) {
  var range = ranges[i];
  Logger.log(range.getA1Notation());
}

Return

Range[] — an array of ranges that serve as this chart's data source

`getTransposeRowsAndColumns()`

If true, the rows and columns used to populate the chart are switched. Defaults to false.

var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheets()[0];

var range = sheet.getRange("A1:B5");
var chart = sheet.newChart()
    .addRange(range)
    .setChartType(Charts.ChartType.BAR)
    .setTransposeRowsAndColumns(true)
    .setPosition(5, 5, 0, 0)
    .build()

// Logs whether rows and columns should be transposed, which is true in this case.
Logger.log(chart.getTransposeRowsAndColumns());

Return

Boolean — true if the rows and columns used to construct the chart are transposed.

`modify()`

Returns an EmbeddedChartBuilder that can be used to modify this chart. Invoke sheet.updateChart(chart) to save any changes.

var sheet = SpreadsheetApp.getActiveSheet();
var chart = sheet.getCharts()[0];
chart = chart.modify()
    .setOption('width', 800)
    .setOption('height', 640)
    .setPosition(5, 5, 0, 0)
    .build();
sheet.updateChart(chart);

Return

EmbeddedChartBuilder — a builder for creating embedded charts
