Extends

OfficeExtension.ClientObject

Remarks

[ API set: ExcelApi 1.7 ]

Properties

autoText	Specifies if the data label automatically generates appropriate text based on context.
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 format of chart data label.
formula	String value that represents the formula of chart data label using A1-style notation.
height	Returns the height, in points, of the chart data label. Value is null if the chart data label is not visible.
horizontalAlignment	Represents the horizontal alignment for chart data label. See Excel.ChartTextHorizontalAlignment for details. This property is valid only when TextOrientation of data label is -90, 90, or 180.
left	Represents the distance, in points, from the left edge of chart data label to the left edge of chart area. Value is null if the chart data label is not visible.
linkNumberFormat	Specifies if the number format is linked to the cells (so that the number format changes in the labels when it changes in the cells).
numberFormat	String value that represents the format code for data label.
position	Value that represents the position of the data label. See Excel.ChartDataLabelPosition for details.
separator	String representing the separator used for the data label on a chart.

top	Represents the distance, in points, from the top edge of chart data label to the top of chart area. Value is null if the chart data label is not visible.
verticalAlignment	Represents the vertical alignment of chart data label. See Excel.ChartTextVerticalAlignment for details. This property is valid only when TextOrientation of data label is 0.
width	Returns the width, in points, of the chart data label. Value is null if the chart data label is not 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.ChartDataLabel object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.ChartDataLabelData) that contains shallow copies of any loaded child properties from the original object.
