What is fade in and how does it work?

[blp]

I'm working with three different bar graphs and I need different bars from
each one to fade into the first sheet, at different times with the click of a
button or other such item.

You're going to have to ungroup the charts, then. It's not possible to mix
and match / reorder animations from different charts.

http://www.echosvoice.com/animate_chart.htm has info about animating a
chart. (Needs work, but it should get you going.)
