Class ContourDataSource

java.lang.Object
org.opentrafficsim.draw.graphs.ContourDataSource
public class ContourDataSource extends Object
Class that contains data for contour plots. One data source can be shared between contour plots, in which case the granularity, path, sampler, update interval, and whether the data is smoothed (EGTF) are equal between the plots.

By default the source contains traveled time and traveled distance per cell.
