Inspect Signal, Run, and Comparison Metadata
When you log or import signals to the Simulation Data Inspector, the software stores both data and metadata. In the Inspect pane, you can find run and signal metadata. In the Compare pane, you can access metadata for the comparison, baseline signals, and comparison signals. To interactively access the metadata, you can:
Add a column to the signal table to display a specific property for all logged signals in the table.
View metadata for a signal, run, or comparison in the Properties pane.
Display Properties in Signal Table
To view the value of particular property for all signals in the signal table, you can add a column to the table. The properties available to add as a column are the same as those in the Properties pane. Some properties, such as Display Scaling or Align By, are specific to either the Inspect or Compare pane.
To choose which signal properties to display in the table on the
Inspect pane, click Preferences
and select Inspect. Select the
columns you want to display from the Inspect - Columns list.
Columns appear in the table in the order in which you select them. To rearrange, click
and drag a column left or right in the signal table.

For example, to add a column to the signal table that shows the approximate storage size of the signals logged to the Simulation Data Inspector, in the Inspect - Columns list, select Size. In the Simulation Data Inspector, the new Size column appears at the right-most side of the signal table and displays the storage size for all signals in the table.

In the Compare pane, create a similar table of signal properties
by choosing from the Compare - Columns list in Preferences
. Many properties available for the comparison signal
table have a baseline signal and a comparison signal version that you can display
independently. When a property does not specify baseline or comparison signal, but both
signals have the property, the column shows data for the baseline signal.
View and Edit Signal Properties
To view all properties for a particular signal, select the signal and expand the Properties pane under the signal table. For some properties, you can edit the values in the column on the right. For example, to change the line color, click the color swatch in the second column of the Line row.

When you compare data, the properties for both the baseline and comparison signal are displayed in the Properties pane.

View Run and Comparison Properties
To view all properties for a particular run, in the Inspect pane, select the run and expand the Properties pane. Scroll through the Properties pane to view all of the properties associated with that run. For example, to view the storage size of a run in the Properties pane, scroll to the Size row.

To view all properties for the runs used in a comparison, in the Compare pane, select the comparison and expand the Properties pane. When you are comparing data, the Simulation Data Inspector displays properties for both the baseline and comparison runs in the Properties pane for the comparison. For example, to view the storage size of the runs in a comparison, scroll to the Size row.
