I'm following the tutorial about creating a range selector (http://www.shinobicontrols.com/blog/posts/2013/02/20/building-a-range-selector-with-shinobicharts-part-i). This works great in a Swift only project as well, except for the ChartAnnotations, which I just can't get to work.
For some reason I can't call the SChartAnnotation constructor with verticalLineAtPosition. I only have annotationWithText for that class. Although that does work as expected, it isn't necessarily what I was looking for.
The same applies for the SChartAnnotationZooming which only grants access to the default constructors(empty, coder, frame).
