Shinobi chart not accessible when inside a scrollview - charts

Question

My application shows an horizontally scrollable area which should contain two different chart implemented using the Shinobi libraries. As my paged Scrollview is made using ATPagingView, I included the chart using the following code:
- (NSInteger)numberOfPagesInPagingView:(ATPagingView *)pagingView {
return 2;
}
- (UIView *)viewForPageInPagingView:(ATPagingView *)pagingView atIndex:(NSInteger)index {
// Instantiate a tutorial item controller and initialise with the proper content
self.chartView = [[ShinobiChart alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];
chartView.title = #"example charts";
chartView.autoresizingMask = ~UIViewAutoresizingNone;
// Use a number axis for the x axis.
SChartNumberAxis *xAxis = [[SChartNumberAxis alloc] init];
chartView.xAxis = xAxis;
// Use a number axis for the y axis.
SChartNumberAxis *yAxis = [[SChartNumberAxis alloc] init];
chartView.yAxis = yAxis;
chartView.datasource = self;
chartView.userInteractionEnabled = YES;
return chartView;
}
The chart gets displayed correctly but, when I try to scroll it, the scrollable container doesn't move to show the second chart. The strange thing is that if I resize the chart in order to have some space to interact with the underlying container or if I do the same operation with a plain view like:
- (UIView *)viewForPageInPagingView:(ATPagingView *)pagingView atIndex:(NSInteger)index {
// Instantiate a tutorial item controller and initialise with the proper content
self.chartView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 100, 100)];
return chartView;
}
well..it works perfectly.
It looks like the ShinobiChart view is somehow intercepting the touch event and not forwarding to the scrollview. As you can notice I tried to activate the user interaction but it doesn't work. Boxing the chart inside another view doesn't work either.
Any idea?

Found a possible solution here. Apparently is a well know issue and the only workaround is to disable pan gestures for the view containing the chart.
chartView.gesturePanType = SChartGesturePanTypeNone;
