Trend view
The Trend view displays a historic trend for one or more register variables. 
Show picture
- In TouchVue, it can be opened from the Variable Details or Dashboard views.
- In SnapVue, it can be opened from the Variable Details view or a tile on the Home view.
If the Trend view is opened from a Variable Details view, then only that variable is plotted.
If the trend view is opened from the Dashboard view, then all variables that have been selected (in the Browsing view) are plotted.
Screen features
- If the variable is being recorded for archiving, the historical values are retrieved and displayed with a solid trace.
- If the variable is not recorded, the Trend view plots the values in real time with a dotted trace.
- By default, the Y-Axis auto scales according to the minimum and maximum value of the variable within the displayed period.
- The pinch open and pinch close gestures can be used to change the X-axis.
