Modifying item display characteristics
To improve the readability of your plot, you can modify the display characteristics including
the item name, color, and size. If you have copied an item to another tab, the changes to the
display properties of this item are only applied to it on the active display tab.
Modifying expressions
The plotter’s graphical representations of items and values are based on “expressions”,
which are text descriptions of the information to be plotted. This use of expressions makes it
possible to create new items based on existing expressions (see Creating and deleting
display tabs and items on page 215) and export expressions to a text file for import into a
later simulation in STVD or into another software (see Exporting and importing plotted items
on page 218).
The time translation (start point), time scale and expression can be changed for copied or
imported items. It is not possible to modify the expressions for items that are updated during
simulation or for sub-items.
To change the expression for the selected item, select Edit>Change Expression. In the
Change Expression dialog box, you can modify the expression for an item by specifying:
● Time Translation – specifies in nanoseconds, the point in the simulation plot where the
plotter will start drawing the specified item. Default is zero: start at time=0.
Entering a
value less than zero shifts the start point for the specified item to the left of the start of
