Loss of formatting on chart (not pivot)

[Raph]

Hi,

I've created a custom chart (stacked bar chart and line on two axes) and I
am displaying the data labels. In particular, I am displaying the total for
the columns buy using a dummy stack and formatting the stack to be clear and
borderless.

I have formatted the data labels, but when I reopen the file, the formatting
on the total data label is lost.

This is not a pivot chart, nor is the data linked to a pivot table.

Any ideas?
