Hi,
I have a a double line graph showing the volume of something over a couple days. I made this fine, using date and the volume. I also have by the hour for each day in a separate field called hour. I was wondering if anyone knew how to super impose specific hours onto the graph, preferably with a caption ie on the 10th of August at 11. I dont want every hour from every day, just certain hours on certain days. it would have the vertical line (or something) and say what happened at the top of said line? Or something to that effect.
