Add data labels
Click the chart, and then click the Chart Design tab. Click Add Chart Element and select Data Labels, and then select a location for the data label option. Note: The options will differ depending on your chart type. If you want to show your data label inside a text bubble shape, click Data Callout.

Right-click on the chart, choose “Add Data Labels,” and the values will appear on each data point. Data labels make it easier to interpret the chart by providing exact data representation for each element. You can customize their position, format, and additional information displayed depending on your preferences.
