  ptolemy.plot.Plot.Bin

Enclosing class:

Plot

private class Plot.Bin
extends java.lang.Object

A bin is represents a number of points that are all displayed on the same x position. A bin is meant to avoid superfluous drawings of lines. So instaed of having to draw a line between each point, you can draw a line between the minimum and maximum and maximum y position.

Method Summary

void	addPoint(PlotPoint point, int pointIndex, long ypos) Add a point to the bin, with a certain pointIndex (the index in the array of all points in a Plot), and a certain ypos.
int	afterLastPointIndex() Return the position after the last point of the range of points within the bin This index is the index within the current points of the plot.
boolean	errorBar() Return true in case there is one point that needs an error bar, otherwise false
int	firstPointIndex() Return the position of the first point of the range of points within the bin This index is the index within the current points of the plot.
long	firstYPos() Return the y position of the first added point in the bin.
boolean	isConnected()
boolean	isConnectedWithPreviousBin() Return true a line has been drawn to the previous bin.
long	lastYPos() Return the y position of the last added point in the bin.
long	maxYPos() Return the maximum y position of the bin.
long	minYPos() Return the minimum y position of the bin.
boolean	needConnectionWithPreviousBin() Return whether a line should be drawn with the previous bin.
boolean	needReplot() Return true when the bin should be plotted (again)
int	nextPointToPlot() Return the position of the next point of the bin that should be plotted This index is the index within the current points of the plot.
boolean	rangeChanged() Return true when the rangeChanged

Method Detail

addPoint

public void addPoint(PlotPoint point,
                     int pointIndex,
                     long ypos)

Add a point to the bin, with a certain pointIndex (the index in the array of all points in a Plot), and a certain ypos. Precondition: The xpos of the point should be same as other points already within the bin

afterLastPointIndex

public int afterLastPointIndex()

Return the position after the last point of the range of points within the bin This index is the index within the current points of the plot.

errorBar

public boolean errorBar()

Return true in case there is one point that needs an error bar, otherwise false

firstPointIndex

public int firstPointIndex()

Return the position of the first point of the range of points within the bin This index is the index within the current points of the plot.

firstYPos

public long firstYPos()

Return the y position of the first added point in the bin.

minYPos

public long minYPos()

Return the minimum y position of the bin. Precondition: only valid in case there is at least one point

lastYPos

public long lastYPos()

Return the y position of the last added point in the bin. Precondition: only valid in case there is at least one point

maxYPos

public long maxYPos()

Return the maximum y position of the bin. Precondition: only valid in case there is at least one point
