Excel.ChartDataTable class

  • Reference
Package:
excel

Represents the data table object of a chart.

Extends
OfficeExtension.ClientObject

Remarks

[ API set: ExcelApi 1.14 ]

Properties

context

The request context associated with the object. This connects the add-in's process to the Office host application's process.
format

Represents the format of a chart data table, which includes fill, font, and border format.
showHorizontalBorder

Specifies whether to display the horizontal border of the data table.
showLegendKey

Specifies whether to show the legend key of the data table.
showOutlineBorder

Specifies whether to display the outline border of the data table.
showVerticalBorder

Specifies whether to display the vertical border of the data table.
visible

Specifies whether to show the data table of the chart.

Methods

load(options)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
set(properties, options)

Sets multiple properties of an object at the same time. You can pass either a plain object with the appropriate properties, or another API object of the same type.
set(properties)

Sets multiple properties on the object at the same time, based on an existing loaded object.
toJSON()

Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that is passed to it.) Whereas the original Excel.ChartDataTable object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.ChartDataTableData) that contains shallow copies of any loaded child properties from the original object.

Property Details
