    I made a new stp file. Prior to running an analysis I punched in numbers starting at 0 for the aliases. I use the signaltap text file to lift the signal names when I record the results of the analysis. When I ran the analysis the arrows magically appeared. I did not even add time bars.

Thank you for replying. I learned from this exchange that the export to BMP function does not show the arrows. I provide a screen shot. I was fiddling with the master and reference time bars trying to enable the arrows. Per your reply, I tried selecting a signal but was unable to activate the arrows.

So you're saying you see the Value column but no arrows above it?

I click where it says "Click to insert a time bar" and the Value column and the arrows appear.
