PowerPoint adds the datasheet to the chart.
By default, when you finish creating a chart, it displays on your slide without the datasheet that you used to enter values. You can, however, choose to display the datasheet as part of the chart to show your audience how you created the chart, or to print out with the slide.
Removing the Datasheet
To remove the datasheet from the chart, double-click the chart, and then click the Data Table button again. The button toggles the datasheet on and off.
