I assume you're referring to the Cost and Volume worksheet. However, I'm not sure I understand what the desired view is. Could you go into more detail?
Tracy, sure thing. I am trying calculate the total effect of price increases across a product line and sorting that by item. By total price increase, I am referring to the last cost - the first cost * quantity ordered over various time frames. I managed to get the correct number by using reference lines and following this example (http://community.tableau.com/message/129304#129304) but am still working to sort this view. In my dataset, I am working with thousands of items, so I am trying to show a high level summation of how increasing prices are hurting the company.
Does this make more sense? Thanks so much for the help!
