Pens configuration (Pens tab)
Each Trend object (historical or dynamic) allows you to simultaneously view a maximum of 16 trends.
Note: The sixteen displayed values must belong to the same sampling group
Each trend is identified by the pen with which it is drawn.
The term Pen refers to a displayed measure, scale, line format, label format ...
The Pens tab, shown in the figure, allows you to define the sampling group linked to the trend and to configure the pens, i.e. the trends drawn:
The sixteen assignable pens are displayed in the list on the left; by selecting a pen, the Pen Data group displays the related configuration data and allows its editing.

The Sample group field on the Pens tab allows you to specify the sample group associated with the current trend.
The "..." button relative to the field allows you to select the group from a list of associable groups:
