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.
