Represents a collection of all the data labels on a chart point.

Extends
OfficeExtension.ClientObject

Remarks

[ API set: ExcelApi 1.1 ]

Properties

autoText

Specifies if data labels automatically generate 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

Specifies the format of chart data labels, which includes fill and font formatting.
horizontalAlignment

Specifies the horizontal alignment for chart data label. See Excel.ChartTextHorizontalAlignment for details. This property is valid only when the TextOrientation of data label is 0.
linkNumberFormat

Specifies if the number format is linked to the cells. If true, the number format will change in the labels when it changes in the cells.
numberFormat

Specifies the format code for data labels.
position

Value that represents the position of the data label. See Excel.ChartDataLabelPosition for details.
separator

String representing the separator used for the data labels on a chart.
showBubbleSize

Specifies if the data label bubble size is visible.
showCategoryName

Specifies if the data label category name is visible.
showLegendKey

Specifies if the data label legend key is visible.
showPercentage

Specifies if the data label percentage is visible.
showSeriesName

Specifies if the data label series name is visible.
showValue

Specifies if the data label value is visible.
textOrientation

Represents the angle to which the text is oriented for data labels. The value should either be an integer from -90 to 90 or the integer 180 for vertically-oriented text.
verticalAlignment

Represents the vertical alignment of chart data label. See Excel.ChartTextVerticalAlignment for details. This property is valid only when TextOrientation of the data label is -90, 90, or 180.

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.ChartDataLabels object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.ChartDataLabelsData) that contains shallow copies of any loaded child properties from the original object.
