How to rotate bar chart like the example "CPTTestApp-iPhone" provided in core plot?

I am trying to have my bar chart have the same rotate behaviour as in the example provided in c开发者_如何学Pythonore plot. I am using xcode4 and been googling with no luck for a while to get this working . If i copy my code in the example it does work fine, how can I do it for my own project? See images below

Portrait

Landscape

Add this:

$self.hostingView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);$

Credit isn't mine, the answer was also on Stack Overflow somewhere else...can't find it.

PS: Obviously replace <self.hostingView> with whatever CPTGraphHostingView you allocated to host your graph and plots in.
