Hello,

My spreadsheet is getting very large, 300+ rows and 25+ columns, most cells
contain formulae. There is also a complex bar chart on the sheet.

Whenever I add new data it seems to take a long time ( a few seconds) to
update the spreadsheet. This is not a major problem but can be annoying when
I have a lot of new data to add.

I have wondered about turning off the 'automatic' re-calculation option and
calculating manually.

Does anyone have other ideas or suggestions please ?

Thanks

KK
