The Preview Pane is a grouping of window panes that change and update dynamically depending on the watch item(s) selected.

The tabs at the bottom of the Preview Pane show the different type of data that may be displayed:

• Real-Time Chart - A chart that plots the response time of the selected watch item(s) which is updated in real-time
• Output - A view of the last saved output for the selected watch item(s)
• Log - A real-time view of a single watch item(s) log
• Performance Chart - A chart that plots the response time of the selected watch item(s) which can be presented 10 different ways.

The preview pane can be hidden, moved, and re-arranged.  See Window Pane Layout for more details.
