I am looking to have an interactive graph that graphs the data attached. In light blue above each column of data to be graphed are 7 rows of data that describe each issue. Below that in column format is the yield to MMD for that issue. At the far right is the average yield to MMD by each year, which is just represented by yr 1, yr 2, yr 3, etc. So yr 1 has an avg, yr 2 has an avg and so on. In another column is an adjusted average spread which I would like to adjust based on selecting critera that would show up in the 7 rows above each column. But I want to be able to have multiple criteria. For example one of the data that shows up above the column is BQ or NON BQ. I would like to be able to select say BQ and only have the Adjusted Average Column sum up and average the columns that have a BQ. The same goes for each of the describtions in Rows 5-10 above each column. But I would like to base this potentially on 1 to 5 critieria. So for instance I may want to sum and average only the BQ issues in 2006 with an A1 underlying rating, or maybe sum and average BQ issues in 2006, with and A1 rating and a par amount above $20,000,000. I will be adding columns over time so will need it to be expandable. The ultimate goal is to be able to graph the adjusted average spread column so that as criteria are selected the graph changes. I am just not quite sure how to approach this and hoping for some suggestions. Thanks for any help you can provde.
