Hi,

I am attempting to show some data in a logarithmic plot but i have some of the data is negative. I know i can't plot negative data in logarithmic plots and i don`t want to convert this data to positive values but is there any way of turning off the alerts.

Cheers for you help
 

Excel Facts

Links? Where??
If Excel says you have links but you can't find them, go to Formulas, Name Manager. Look for old links to dead workbooks & delete.
Why is the data negative in the first place? Is there an error somewhere else, or are negative entries valid?

To plot on a log scale, use another column as your actual series anything <=0 would return a "N/A", else the actual data. This is untested, but should work.

example:

=IF(A1<=0,NA(),A1)

Hi Jay,

Thanks for the reply. Most of the data is positive but occasionally it can become noisy which means it goes below zero.

I had thought of using another column but i was wondering if the alerts could be turned off.

Thanks for your help anyhow
