hide labels during animation

[Giampaolo Trapasso]

Hi to all,

i would like to hide labels during an animation of a plot. I thought that I could use a flag "animationIsRunning" and use it in 

-(CPTLayer *)dataLabelForPlot:(CPTPlot *)plot recordIndex: (NSUInteger)index 

to return labels when flag is false and return nil when flag is true, forcing a reload of data. Is there a different (may be more elegant) solutions?

Thank you in advance.

No. Reload once to remove the labels and again to put them back.

Thank you for your reply. I'm going to follow it. But a question more arises: why this code does not do what i'm looking for?

for (CPTPlotSpaceAnnotation *a in _masterPlot.annotations) {

                [a.contentLayer setHidden:YES];

I would like to understand a bit more about plot space annotation class.

That should work, too.
