Easy Question: What is the term for putting red / yellow / green symbols

[bd_atl]

in a report.  I am searching like crazy for a tutorial / example of how to do conditional formatting in a table to show red/yellow/green symbols in a report.  (I'm building an Active Report BTW) I cannot find a direct example with this on the web.  Can anyone point me in the right direction?

Thanks,

Ben

Here is an example using the sample packages/data for Cognos, from IBM's online documentation.

This is called a traffic signal report. It is done by conditional formatting :D
