Hi,
I'm working with fairly large datasets, ~10k lines in 6-10 columns. The
data are elevations taken on the hour, every hour for a year or two. When I
graph these in 2007, I use a connected scatter plot, just as I would in 2003.
Excel happily works with the data and creates the graph, but doesn't always
get the vertical axis scaling how I want it. As soon as I try to fix the
values for this axis where I need them, the program slows to a crawl.
Spreadsheet functions still work fine, but anything involving the chart is
slow. For example, a right click on the series in the chart will take at
least 10 minutes to register, if it does at all. In the meantime, Excel
freezes completely.

I've tried to recreate the problem with smaller data sets, but it doesn't
seem to do anything wrong. Is this a problem with my data set or with excel?

Thanks
-Tom
