Zeros on a logarithmic scale

By definition zeros cannot be represented on a logarithmic scale.  So, a log graph which contains zeros is problematic.  Is there a way to get Excel to ignore these values and stop giving persistent error messages?

You can add an IF inside your formula:


Something like

=if(a1=0, 'No zeros on logaritm', log(a1))

Hope it helps

Thanks for the suggestion, but where would I add the formula as I am building the chart to make it ignore the zeros?

if you want to ignore, I think you should force an error value, such as an empty string. Put the if inside the formula you have and see what happens in graph.
