Graph with pivot table

[Guest]

Hello
I have a custom graph which has both stacked columns bar and a line graph
with pivot table. Everytime I refresh data, the graph switch to graph with
colums bars.
How can I lock a graph to prevent switching?
Thanks a lot, R.

Loss of formatting is a known problem with pivot charts. There's
information in the following MSKB article, suggests recording a macro as
you apply the formatting:
