Charting a complicated function in Excel
Thursday, March 23rd, 2006... Use a Data Table
I used to know how to do this, but then forgot i) how to do it, and ii) what it was called.
You can fill a range of cells in Excel to the output from whatever arbitrary formula you would like, by making a list of input values, and the output formula at the top. This is useful because you can have the output being the result of some worksheet which is too complicated to manage in a single formula. The inputs can be applied to any cell you want.
So. 20 minutes of joy trying to navigate MS help and Google before I found what I needed.
