isUpdatingEnabled
Flag determining if view is allowed to recreate internal rendering data structures (YES) or not (NO). The default
value is YES.
Use this flag to temporary lock the updating of the view. You may need to lock it (by setting NO to this
property) in viewWillDisappear of your view controller and unlock it (by setting YES) in viewWillAppear. This kind of
locking helps to avoid troubles related to the updating of invisible OpenGLES-based views (because in iOS 8+ such
updating leads to OpenGLES crash).

– waitForUpdating
Wait for rendering (by pausing calling thread until rendering thread does its job).
Use this method whenever you want to guarantee the settings you made in your objects are reflected on
the view (for example, by hiding settings screen to guarantee user wont see the last frame of old data).
- (void)waitForUpdatingDiscussion
You do not need to call flushChanges method of the NChart object if you use this
method: the data are synced automatically.
