Figure 40. The Profile Tab 

The Histogram Tab

The

Histogram

 tab provides a summary of the pixel data presented on the previous 

screens.

The histogram displays temperature values as either a percentage of the all temperature 
values captured in a given thermal scene, or by number of representative pixels in the 
thermal scene. 

To view a subset of the data, you may select 

Limits

 on the 

Images

 > 

Histogram

 menu, 

and enter the specific maximum and minimum temperatures for the data you are interested 
in graphing.
