Two graphs in the same graph????

[astensland]

I'm looking to create a Graph that is essentially two graphs. (i.e. overlay a area graph with a line graph). The data going to each graph comes from the same datasource. The datasource is a dataset (xsd file). So far I have only been able to add one graph. Does anyone know how to add both? I found something about selecting a series, right clicking and then select edit current object. But I didn't unserstand that... What series? Can someone please tell me this in a step by step manner what I need to do(since I am a crystal reports dummy...)??....
Thanx
