You can choose to hide the Key so that the Trend makes maximum use of the display area. This is useful when you only need to view the trace and have no need for the information in the Key (or the options to which it provides access).
To hide and show the Key:
- Right-click in the main display area on the Trend.
A context sensitive menu is displayed. - Enable or disable the Show Key option as required.
The key is shown or hidden depending on whether you enabled or disabled the option.
