Regard's,
I have a bar chart is a project cost of summation. In this chart I need to have two vertical lines where :
Topline is the upper limit and the lower the minimum limit cost of a project. The bottom line is 80 % of the estimated total project cost and the top line represents 120% of that cost
You can enter these two lines in a bar graph without series , as in the image below :
