Special Effects
· Avoid special effects if they do not enhance the point to be made.
· Use of 3-dimensional bars may make reading the data a little more difficult because it is not evident which part of the 3-D bar measures actual data.
· Use 3-D graphs if you have three axes of information.
· Build a series on a 2-D version of the chart to add some distinctive effect(Figs. 24 and 25).
· Consider breaking the graph or figure into components (i.e., add segments,build, or use more slides to show the graph).
· You can show the entire graph and then focus in on a certain part that really displays the information you want to get across.
