I understand why you got the data labels for the min/max/base values of the lever varaibles, but in the screencast I couldn't decipher the steps to get those values on screen.
Very elegant solution, by the way. Thanks!

How do you add the title to the chart? Thanks.

I would also add – print function to make useful instruction available off-line

@guillaume – You are right – the tornado shows independently the effects of each assumption. Unfortunately there isn't a one-size-fits-all for combining the assumptions. I've used Monte Carlo simulation as an effective way to show these "combined effects". That usually requires your audience to be very familiar with modeling, the particular problem, and you doing a good job at communicating the analysis in a simple way. Usually I try to "peel back" the root-cause analysis when assumptions are not too orthogonal. Conversely, when two assumptions are too coupled, I just show one of them in the tornado and verbally mention the second one, explaining why in fact they are considered together.

Hi – when you choose "set the Axis Labels menu to Low" (end of step 4) the labels should move to the left

Very simple and useful! thanks a lot!!
Quick question: tornado charts assume that each assumption does not interact with the others.
Do you have simple models that would combine all assumptions (by affecting a probability % on each assumption for example)?

How do you move the axis labels to the left. You don't mention it in the excel 2003 version either.

Just added them to make clear to the audience the values on the assumptions that change the results

in the screencast it doesnt show how you got the data labels to represent to the max/mins of the y axis
