Please correct me if my understanding is not right :
I think persistent objects (sheets and chart objects) without show/hide conditions are not calculated but consume tiny memory to store properties. But if there is show/hide condition in the sheet/chart properties then the calculation is done and full memory is used. Is this right?
Also, I wanted to understand how accurate is the memory statistics? Some of the simple chart objects consume high memory and high calculation time. Please can you explain?
