Excel.ChartLineFormat class

Package:

excel

Encapsulates the formatting options for line elements.

Extends

OfficeExtension.ClientObject

Remarks

[ API set: ExcelApi 1.1 ]

Properties

color	HTML color code representing the color of lines in the chart.
context	The request context associated with the object. This connects the add-in's process to the Office host application's process.

Methods

clear()	Clears the line format of a chart element.
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.ChartLineFormat object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.ChartLineFormatData) that contains shallow copies of any loaded child properties from the original object.
