How can i change the default line weight in an excel chart

[Guest]

I select a heavier line weight for a Pivotchart graph so it is easier to see,
however every time i change something on the graph from the drop down box the
line weight goes back to it default (lighter) weight.

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:
