Class FillPlan

java.lang.Object
  uk.ac.starlink.ttools.plot2.layer.FillPlan

public class FillPlan
extends Object

Plan object for fill plots. This is an unweighted pixel density map (2d histogram), plus some additional compact information describing the data that falls outside of the plot density map.

Method Summary

static FillPlan	createPlan(Surface surface, DataSpec dataSpec, DataGeom geom, int icPos, DataStore dataStore) Creates a fill plan object.
Binner	getBinner() Returns the object containing density map pixel counts.
Point	getCpXhi() Returns the closest point to the upper X boundary that falls outside the grid.
Point	getCpXlo() Returns closest point to the lower X boundary that falls outside the grid.
Point	getCpYhi() Returns the closest point to the upper Y boundary that falls outside the grid.
Point	getCpYlo() Returns the closest point to the lower Y boundary that falls outside the grid.
Gridder	getGridder() Returns the object encapsulating grid geometry.
int[]	getXhis() Returns array of bins containing all points below each pixel column.
int[]	getXlos() Returns array of bins containing all points above each pixel column.
int[]	getYhis() Returns array of bins containing all points to right of each pixel row.
int[]	getYlos() Returns array of bins containing all points to left of each pixel row.
boolean	matches(DataGeom geom, DataSpec dataSpec, Surface surface) Indicates whether this map's data is valid for a particular context.
