I'm evaluating Shinobi Charts as a charting solution for a project I'm working on. I have a problem positioning an annotation on a chart.
I have a simple line chart and I need to display an annotation when a data point gets tapped. I'm creating and adding the annotation to the chart in the delegate method sChart:toggledSelectionForPoint:inSeries:atPixelCoordinate: I've tried manually setting the frame of a annotation and also subclassing SChartAnnotation and setting it there. Whatever I do, it doesn't seem to work. The annotation is always centered on the data point which is no what I need.
What is the prefered way of positioning an annotation on the chart?
