One popular trick is using the Callouts available under the AutoShapes button on the Drawing toolbar. They look sort of like dialogue bubbles in cartoon strips. Just drag the Callout onto the chart and then use the tail’s handle to drag the tail down to the item you’re highlighting. Click in the Callout to enter text such as, “Highest satisfaction rating in 10 years!” Note that your Callout is not part of the chart; it is just another item in the worksheet. To ensure the Callout is visible on top of the chart, right-click it and choose Order and Bring To Front.
