IGSplineSeries Class Reference

Overview

IGSplineSeries displays a curved line that passes through each of the series data points, with string labels along the X axis and numeric values along the Y axis. This series uses IGCategoryXAxis or IGCategoryDateTimeXAxis and IGNumericYAxis. The data source for this series is a collection of single value, single label points. IGCategorySeriesDataSourceHelper can be used as the data source for IGSplineSeries.

Multiple series of the IGSplineSeries type are handled the same, regardless whether or not they share the same X axis. The line series with the higher index will be drawn in front of the previous series.

Markers, when enabled, are placed at the locations of data points.
