Yo.

Just an inexperienced excel user playing around trying to track my sleep and make a graph out of it. So I have made this test graph



I was just wondering if it was possible for me to make my own line through the column chart, like if I want to sleep 8 hours, and that is the target, is it possible to put a bar going through the graph with 8 hours?



For example like I have done here, this is done manually by using a 'shape' in excel. But is it possible to do it automatically through the chart program or no?
