Prevent a dynamic line chart from interpreting formula output of "" as 0?

[wrecclesham]

I have a formula in a table that uses an IF function. The output of the formula dynamically plots a line chart.

The problem I'm experiencing is that if the output of the IF function is False, then the "" value output is interpreted by the dynamic line chart as a zero instead of a blank cell, and a line is plotted at 0.

What is supposed to happen is that nothing should be plotted at all where the formula outputs "".

How can my formula output a blank cell output in such a way as to prevent the corresponding dynamic line chart from treating it as a "0" and plotting a line through zero?

Have you tried replacing the "" result of the formula with NA()

=IF(Test,Positive,NA())

Great. Thank you.

I was initially trying to get the table to show a blank cell but I now realize that that wasn't important and it's fine if it shows #N/A. The only thing that matters is that the graph plots the right lines and that it plots nothing at all where it's not supposed to.

Your solution looked different to what I was expecting but actually does exactly what I wanted! Very cool.

No worries, glad to help.

If you want the appearance of a blank cell then you can always use Conditional Formatting to hide it.

'Conditional Formatting > New Rule > Use a Formula to determine...'

Using A1 as an example, use;

=ISNA(A1)

As your formula.

Format the condition so that it appears "blank" (white on white text, etc.)

Hope that helps
