I'm looking for help to create a chart in excel. I want to illustrate a cost for disk space using one line, and then the other line show the growth of disk space, both over a 5 year period.

Ideal, top portion of graph has year 1,2,3,4,5
Side shows Terrabyte increments (i.e. 1.5,1.8,2.1,2.5)
Bottom would have dollar amount (i.e. 50,000,80,000.....)

Is this possible?
