Graphs on Crystal Reports 10

Hi all,

I have recently started using Crystal Reports and my knowledge with it
is relatively limited. I am currently attempting to create 2 different
types of graphs that I am struggling with and was hoping someone out
there could help!!

1. How do I create a graph that uses a formula field as the data
series?

2. How can I create a graph that displays multiple data series on a
line and column basis using seperate axes?

Thanks in advance for your help

Matt
