Calculated Chart Titles

Hi Everyone,

I have a sheet that contains many hidden charts. I was asked to make the chart titles dynamic but I remember reading somewhere that even though a chart is hidden (not minimized) the chart title is still calculated. Does anyone know if this is true? or where I can find some more information on it? I understand that the chart title would be calculated in the chart is minimized, but don't know about when the chart is hidden by a show/hide condition.

Hi,

Not really, I have the calculation condition figured out. In the chart title, I want to put "filtered" in the title, something like ='My Chart Title ' & IF(ISNULL(getcurrentselections()),'','(Filtered)'). But I don't want to incur the extra calculation time when the chart is not displayed.

Lucas,

I'm not positive, but I think you're correct that chart titles are always calculated. This is necessary for the object to be displayed in the Document Properties window (which is the only way you can unhide it manually). That window lists all objects and they need to have a title...

Regards,

I wouldn't worry about the calculation time in this case. The time required to establish that chart title should be effectively 0 on any modern computer. If you want to verify my guess, make a text box with that title in it. Fiddle with the selections. Go into the sheet properties, objects tab, and check the CalcTime. I'm betting it's 0. Obviously it takes SOME time, but not enough for the computer to notice.
