Anything that involves much more than default formatting of Excel 2007
charts is likely to increase the time it takes the chart to redraw. I
suspect in the upcoming SP1 (don't ask when it's expected) that issues like
this will be improved.

Hi,

using excel (Microsoft office 2007), when I try to format a line in a
graph
my worsheet either takes forever, or completely freezes before I can edit
the
line. All I want to do is change the line from being a red line to being
a
dotted black line, for example. The data that is in the graphs is stored
in
another excel file, which I think makes it work more slowly as well. Has
anyone else had that problem? is there an update for it?


Thanks,

Christina
