You can highlight the data in a chart by changing the appearance, position, or spacing of one or more data series. A data series is the set of related values represented by each bar, pie slice, line, and so on, plotted on the chart.
You can show straight or curved connection lines in line or scatter charts, or remove the lines in scatter charts (so you see only the data points).
Select the pie or donut chart.
