I've been using Excel to develop a tornado chart in a sheet I'm using.

I've used a stacked bar chart with a blanked out first bar to float the
remaining bar(s) - and this has worked fine - and I have managed to get
the chart to be able to automatically reflect scenarios where the
min/max values are both negative, positive and a positive/negative mix.

The last task that I want to do is to put a single 'line' on the chart
to indicate the baseline value of the tornado - so it runs top to
bottom through the bars.

As this is going in a model I want this to be automatic rather than
hardcoding this into the chart

Any ideas - its annoying me to death

Thanks for the reply

I've actually managed to put in the line I wanted down the average
value by reseting the y-axis to cross the x-axis at the average value
rather than the 0 default - this has worked well

So basically I've now got an in-sheet method based on 4 cell based
formula per sensitivity parameter which I then feed into a stacked bar
chart - and then I reset the y-axis crossing

This produces a nice looking Tornado plot without the need for an Excel
add-in

I'll post this as an example when I get time to tidy it up a little

Steve -

If you want to write it up, I could post it on my site as an alternative to
