Why sheet charts appear with X on them

[DanielBeck]

Hey everyone.

I have a question and maybe you can help me. 

Why all my sheet charts appear with Xs on them like in the picture below:

Thanks,

Daniel.

Hi, it menas that the charts couldn't be calcualted, maybe beacuse some complex expression that goes above the defined timeout to calculate objects, if you move to another sheet and go back they should try to calculate again. Go to another sshett and do some selctions to reduce data to calculate..

If this is the case the reason usually is an unoptimized data model that needs a lot of resources to calculate
