Urchin 6 - Radio spots overlay

Want to measure effect of radio spots on my visitors

[SEOtop10]

Hi

Do you use Urchin 6 - on demand tracking? I am greatly impressed by the wealth of information it provides. I want to go further.

Actually we run radio spots at certain times and I want to overlay the schedule on the traffic charts so that I can gauge the effectiveness of the radio campaign. May be I will like to highlight the 1 hour period after every ad to see if there is any spike.

Can you help me do this?

Why not use a unique URL like a subdomain or folder or even a seperate domain? It would be much more accurate.
