If a lookup object is shared (in either a global data source or in another picture), you can use its color table to define a threshold.
On the Color Expert, click the Use Shared Table check box and then, in the Shared Table field, enter the data source for the shared color table. Click the Browse button to make a selection from a Picture or a Global data source available in your system.
You can open the Color Expert by clicking on the Color Expert button in the toolbox, or by selecting a specific Color Animation in the Basic Animation dialog box.
