Excel.ChartLegend class

Package:

excel

Represents the legend in a chart.

Extends

OfficeExtension.ClientObject

Remarks

[ API set: ExcelApi 1.1 ]

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 formatting of a chart legend, which includes fill and font formatting.
overlay	Specifies if the chart legend should overlap with the main body of the chart.
position	Specifies the position of the legend on the chart. See Excel.ChartLegendPosition for details.
visible	Specifies if the chart legend is visible.

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.ChartLegend object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.ChartLegendData) that contains shallow copies of any loaded child properties from the original object.
