Is there some way to tell @RISK what descriptions to use for the bars in tornado charts?

Yes. The bar labels in tornado charts come from the names of your @RISK input distributions. Each input has a name that @RISK uses in graphs, reports, and the Model Window.

When you first define a distribution, @RISK tries to create a default name from nearby row or column headings.

• If that name is fine, you can leave it.
• If it’s unclear or blank, you can change it in any of these ways:

1. Define Distribution window
   Open the Define Distribution dialog and enter the desired name in the first box. You can do this when creating the distribution or by reopening the dialog for an existing one.

2. Model Window
   Open the Model Window, right-click the input, choose Function Properties, and edit the Name field.

3. Edit the formula directly
   Insert a RiskName property into the formula. Example:
   =RiskPoisson(.234, RiskName("Number of claims"))

4. Reference a cell:
   =RiskPoisson(.234, RiskName(A17))

5. Combine cells:
   =RiskPoisson(.234, RiskName(A17 & " " & A18))

Avoid complex Excel table notation in names, since not all versions of @RISK interpret it reliably.

After changing names, save the workbook. New tornado charts and reports (after rerunning the simulation) will use the updated descriptions.
