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: Interfaces.ChartTitleUpdateData, options?: OfficeExtension.UpdateOptions): void;Parameters
- properties
- Excel.Interfaces.ChartTitleUpdateData
A JavaScript object with properties that are structured isomorphically to the properties of the object on which the method is called.
- options
- OfficeExtension.UpdateOptions
Provides an option to suppress errors if the properties object tries to set any read-only properties.
Returns
void
set(properties)
Sets multiple properties on the object at the same time, based on an existing loaded object.

A string that represents the formula to set.
Returns
void
Remarks
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.ChartTitle object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.ChartTitleData) that contains shallow copies of any loaded child properties from the original object.
toJSON(): Excel.Interfaces.ChartTitleData;Returns
