I'm trying to create the bubble chart illustrated in the attached .png file using Telerik UI for iOS. The features I need that I can't figure out how to create are:
-- Changing the color of each bubble in the series
-- Adding an annotation next to each bubble.
I thought the right way to get closer to this design was to implement paletteItemForPoint in my TKChartDelegate
Toward this, I added these lines to my chart series creation:
bubbleSeries.selectionMode = TKChartSeriesSelectionMode.DataPoint
bubbleSeries.style.pointShape = TKPredefinedShape(type: TKShapeType.Circle, andSize: CGSizeMake(8, 8))
And set my class as the chart delegate
And then implemented paletteItemForPoint
However paletteItemForPoint is never called for my bubble chart. I did the same steps with a line chart and the paletteItemForPoint routine is called as expected.
Am I going about this the wrong way, or is it just impossible to customize a bubble chart in these ways?
