Update a Chart Data Point

Introduction

In PowerPoint presentations, data points are individual values or specific pieces of data that are plotted on a chart. Each data point represents a particular value within a dataset and is typically represented graphically as a marker, bar, line, or other visual element on the chart. Use the following method to update data points of a chart in presentations.

UpdateChartDataPoint

API Information

API	Type	Description	Resource
/slides/{name}/slides/{slideIndex}/shapes/{shapeIndex}/series/{seriesIndex}/dataPoints/{pointIndex}	PUT	Updates a data point of a chart in a presentation saved in a storage.	UpdateChartDataPoint

Request Parameters

Name	Type	Location	Required	Description
name	string	path	true	The name of a presentation file.
slideIndex	integer	path	true	The 1-based index of a presentation slide.
shapeIndex	integer	path	true	The 1-based index of a shape (must be a chart).
seriesIndex	integer	path	true	The 1-based index of a data series.
pointIndex	integer	path	true	The 1-based index of a data point.
dataPoint	`DataPoint`	body	true	The data transfer object of the data point.
password	string	header	false	The password to open the presentation.
folder	string	query	false	The path to the folder containing the presentation file.
storage	string	query	false	The name of the storage contaning the folder.

Examples

In the default storage, the document MyPresentation.pptx contains a scatter chart (the second shape) that displays the number of items sold for quarters 1 through 4 (one data series). Update the sales value for the 2nd quarter to 10 items.

The referenced shape must be a chart, otherwise the operation will fail.
