This example shows how to create a column chart with data from a data table.
constsampleData=Charts.newDataTable() .addColumn(Charts.ColumnType.STRING,'Year') .addColumn(Charts.ColumnType.NUMBER,'Sales') .addColumn(Charts.ColumnType.NUMBER,'Expenses') .addRow(['2004',1000,400]) .addRow(['2005',1170,460]) .addRow(['2006',660,1120]) .addRow(['2007',1030,540]) .addRow(['2008',800,600]) .addRow(['2009',943,678]) .addRow(['2010',1020,550]) .addRow(['2011',910,700]) .addRow(['2012',1230,840]) .build(); constchart=Charts.newColumnChart() .setTitle('Sales & Expenses') .setXAxisTitle('Year') .setYAxisTitle('Amount (USD)') .setDimensions(600,500) .setDataTable(sampleData) .build();

Detailed documentation
build()
Builds the chart.
Return
Chart — A Chart object, which can be embedded into documents, UI elements, or used as a static
image.
reverseCategories()
Reverses the drawing of series in the domain axis. For vertical-range charts (such as line, area or column charts), this means the horizontal axis is drawn from right to left. For horizontal-range charts (such as bar charts), this means the vertical axis is drawn from top to bottom. For pie charts, this means the slices are drawn counterclockwise.
// Creates a pie chart builder and sets drawing of the slices in a // counter-clockwise manner. constbuilder=Charts.newPieChart(); builder.reverseCategories();
Return
Column — This builder, useful for chaining.
setBackgroundColor(cssValue)
Sets the background color for the chart.
// Creates a line chart builder and sets the background color to gray constbuilder=Charts.newLineChart(); builder.setBackgroundColor('gray');
Parameters
| Name | Type | Description |
|---|---|---|
css | String | The CSS value for the color (such as "blue" or "#00f"). |
Return
Column — This builder, useful for chaining.
setColors(cssValues)
Sets the colors for the lines in the chart.
// Creates a line chart builder and sets the first two lines to be drawn in // green and red, respectively. constbuilder=Charts.newLineChart(); builder.setColors(['green','red']);
Parameters
| Name | Type | Description |
|---|---|---|
css | String[] | An array of color CSS values, such as ["red", "#acf"]. The nth element
in the array represents the color of the nth line in the chart. |
Return
Column — This builder, useful for chaining.
setDataSourceUrl(url)
