Hi,

You need to use the Vertical (Value) axis dialog.
To get this you can select the chart and then select the Format contextual
tab.
In the Current Selection group use the dropdown list to select Vertical
(value) axis. Press F1 if the format dialog is not currently displayed.

One thing I did discover is that if you use the up arrow to cycle through
selected chart elements it does not go through Vertical value axis.
But if you use the Down arrow it does.

One other thing I noticed is the order of bands is reversed to that of
xl2003.

Cheers
Andy
