Answer 1

You have to display data labels (that is what they are called in CorePlot), some good information are here Core-Plot CPTScatterPlot data labels

To show data labels, you'll need to return the corresponding values from

-(CPTLayer *)dataLabelForPlot:(CPTPlot *)plot recordIndex:(NSUInteger)index

Data labels do not appear by default. The automatic labels require both a labelTextStyle and labelFormatter to be set. Both of these properties default to nil which hides the labels.
