Calculated Dimension using Input Fields for Trellis Chart

[#1]

I would like to provide my users an ability to dynamically interact with a large data set to create a customer trellis chart. The goal is to demonstrate changes over a user defined series of periods (weeks, months, quarters, etc).

Example: For a Combination Line and Bar Chart that shows Shipments (Line)  and Returns (Bar) , a user would come in and enter into a series of Input Boxes

Pedigree 0 - 'Baseline'

Start Date

End Date

Pedigree 1 = Change 1

Start Date

End Date

Pedigree n = Change = n

Start Date

End Date

Then the chart would pick up 'Pedigree' as a Dimension and display a trellis of the date from Pedigree Start Date 0 to Pedigree n End Date.

The use would be able to create something like the example below.
