Forecasting

Hello. I have a graph for forecasting that has a line for the 2013 actuals and then the 2013 estimate. The problem is that there is a gap between the actual and the estimate line and it doesn't look good. I've attached a screenshot. Is there any way to make this look cleaner? Maybe a dotted line between, in this case, January and February? Thanks!!

can you add in the dec figures and get a Jan forecast -
