Introduction

Markers are symbols (circular colored shapes) overlaid on the IGSparklineView indicating individual data points based on X/Y ordered pair coordinates.

All markers are set to display, by default, and are customizable to appear in a variety of colors by setting the marker’s brush property to an IGBrush. Set the marker’s visibility property to YES or NO to toggle rendering of the marker on or off respectively.
