I need a graph type that's not standard in Excel.

suppose:
X axis =time in days
Y axis represent e.g. a production qty.
Each day on Xaxis has a target value T and a realized qty Q.
Q can be <T or =T or T.
So the graph will show 2 lines.
If T-line Q-line surface between Q and T must be red
If T-line < Q-line surface between Q and T must be red
For visual management it creates a graph; if you see surface green about
same size as surface green everage will be on target till that date.

Problem: I cannot find that type of graph in the excel graphs.
Does anyone know how to get it?
