You can select the entire chart, choose Copy from the Edit menu, select
another chart, then choose Paste Special from the Edit menu, and use the
Copy Formats option. This copies the formats in the copied chart, as well as
chart and axis title text, so any title in the pasted-to chart are wiped
out.
You can't copy formats of individual chart elements, but what I sometimes do
is format the element I wish to copy, change one thing and change it back,
OK out of the dialog, and select the element in the other chart, and use F4
to repeat the formatting on this object.
