Formatting the Data Labels of the Pie Chart

2) In cell A12, type the text Sinusitis, and give the cell a black border, and align the text to the center position.
3) Select the Unforced Errors data point only, (the currently orange shaded data point), since we now only want to format this particular data point with specific formatting.

10) Select [Cell] Choose Cell from the options.
11) Select the cell reference, which in this case is cell A12, so that if one changes the value in cell A12, i.e., let’s say there was another reason the player was not performing well, then the Data Callout will automatically update based on the value in this cell.
12) Select the Data Callout and position it slightly to the left by just dragging it, and add a space between 74% and Sinusitis as shown.

23) Delete the legend since the information needed, is already displayed in the data callouts and increase the size of the chart to 8.71 cm by 14.45 cm.
And there you have it, the tennis coach at hand now has an analysis of the match errors presented in a visual format and a way to hone in on what the unforced errors were due too. Let’s say post-match he discusses the performance of the player at hand with the assistant coach, and they decide the unforced errors were actually due to lack of concentration – they can update cell A12, and the reason for the unforced data point callout then updates automatically.
Pie charts are useful ways of presenting parts of a whole. They are some of the most used chart types in reports, dashboards, and infographics. Excel provides a way to not only create charts but also to format them extensively so that they can be utilized with ease in presentations, posters and infographics. One can add rich data labels to data points or one point solely of a chart. Adding a rich data label linked to a certain cell is useful when you want to highlight a certain point on a chart or convey more information about this particular point. This can be utilized for statistical outliers as well, and one can label the outliers on a chart for example only in order to shed more insight on these outliers.
