Marker Shapes

Introduction

Markers are visual elements that display data point values in the IGChartView control's plot area. Markers help your users immediately identify a given data point's value, even if the value falls between major or minor grid lines. There are a number of predefined marker shapes available to be used with the chart’s series. An identifying characteristic of those series that support markers is the presence of markerType property, which when set to IGMarkerTypeAutomatic, results in the series index in the chart’s series array determining marker selection.
