Annotate Gchart help?

[SciFiGuy0]

I've got a bar chart showing car and bus accidents over the past week.  Cars and Busses have an average daily rate.   What i'd like to do is annotate the bar graph to add a dotted line for the Car average and the Bus average.   I've marked up the bar graph to show how i'd like it to look (See attached graphic)

I'm not sure how to set up the annotate dataset to add the dotted average lines.   Can anybody help?

Instead of GCHART can you use SGPLOT with VBAR and VLINE instead?
Example is here.

Add a group to vbar/vline to get your two different lines/bars.
