To create a traffic lighting definition:
Right-click a member, and select Analysis Tools , then Traffic Light.
The Traffic Lighting dialog box is displayed.
From Apply To, select the member to which traffic lighting is to be applied.
From Comparing It To, select the member to which the previously selected member is to be compared.
Compare to a fixed limit by, in Assign Limits, deselecting % Differences or, from Comparing It To, selecting Fixed Value.
Select Advanced twice, first to separate members into combinations and second to select from aggregated members.
Assign Limits contains three default set points and colors. Set points divide values into ranges identified by color.
For each set point, indicate a set point operand.
The first list prompts you to specify whether the setpoint value is in the range; you choose greater than (>) or greater than and equal to (>=).
In the text box, enter a setpoint value, to specify the threshold that separates ranges.
The second list prompts you to specify the setpoint value; you enter positive or negative decimal values.
Optional: To change the range color, click Color, and select a color square.
The Color button displays a color-square palette. Selecting a square assigns it to the current traffic lighting range and displays the hexadecimal value of the color in the neighboring text-entry field.
Optional: To change color opacity, enter a value in the last text-entry box for each range.
You can specify a percentage from zero (transparent) to one hundred. Transparency is sometimes used to reveal background graphics.
Optional: To add a set point, click Add to End, and repeat steps 4 through 7.
