Delete a Chart Data Point Introduction In PowerPoint presentations, data points are the individual values or pieces of data represented on a chart. They visually depict specific information such as numerical values, percentages, or other quantitative data. Use the following method to delete data points from a chart in a presentation.
DeleteChartDataPoint
API Type Description Resource
/slides/{name}/slides/{slideIndex}/shapes/{shapeIndex}/series/{seriesIndex}/dataPoints/{pointIndex}
DELETE
Deletes a data point from a chart in a presentation saved in a storage.
DeleteChartDataPoint
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.
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). Delete data for the 4th quarter.
The referenced shape must be a chart, otherwise the operation will fail.
