Excel.ChartPointsCollection class

Package:

excel

A collection of all the chart points within a series inside 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.
count	Returns the number of chart points in the series.
items	Gets the loaded child items in this collection.

Methods

getCount()	Returns the number of chart points in the series.
getItemAt(index)	Retrieve a point based on its position within the series.
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.
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.ChartPointsCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.ChartPointsCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
