How do I animate the appearance of a bar chart in Core Plot?

Question

When first displaying a bar chart using Core Plot, I\'d like the bars to grow upward until they reach their correct heights.

How would you create such an animation usi

Answer 1

Add opacity animation like this...

CABasicAnimation *fadeInAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"];
fadeInAnimation.duration = 1.0f;
fadeInAnimation.removedOnCompletion = NO;
fadeInAnimation.fillMode = kCAFillModeForwards;
fadeInAnimation.toValue = [NSNumber numberWithFloat:1.0];
[xSquaredPlot addAnimation:fadeInAnimation forKey:@"animateOpacity"];
