Standard chart-click-by-click a want arrow lines show on my chart

[modify email template]

I saw a presentation with a Standard chart. Each time he click his mouse, an
arrow show up(he clicked 3 times) then in the end, numbers show up in a box.
(total numbers). How can I perfome these two actions?

PowerPoint allows you to animate components of a chart or animate object
placed over a chart to "enhance" it. See:
