JBBarChartView Bar Height Problem With Storyboard/Autolayout

[xanderdunn]

When I setup my view controllers in a storyboard with autolayout, I end up with a JBBarChartView that starts animating the bars on viewDidAppear, but then the bars just stop and disappear (1st image below). On the other hand, an identical setup that I create in code rather than in storyboard works just fine (2nd image below).

Hey @AlexDunn, since nib's instantiate themselves with initWithCoder:, add the following to your controller:

- (id)initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];
    if (self)
    {
        [self initFakeData]; // fake rain data
        _monthlySymbols = [[[NSDateFormatter alloc] init] monthSymbols];
    }
    return self;
}

I've fixed this issue in the demo project via commit: 3d5e5c3

Oh, I see! Yeah, the problem was just a lack of data when it initialized from a storyboard.

Beyond that, to prevent an exception where the graph view's size has not yet been determined when using auto layout constraints, I had to add my constraints in viewDidLoad and then add my footerView and headerView in viewDidLayoutSubviews.
