The diagrama does not want to correctly display the result of the function

[VShostak]

Hello

The diagrama does not want to correctly display the result of the function " =IF(U:U="";"";U:U-$AI$3) ", diagrama "breaks" when it hits an empty cell created by the function. Is it possible to somehow write an empty cell so that the chart displays correctly.

Thanks

What if you change the formula to:
=IF(U:U="";NA();U:U-$AI$3)

It worked, thanks a lot!
