All Known Implementing Classes:

OHLCVIndexQuoteGraphSource, OHLCVQuoteGraphSource, PortfolioGraphSource

public interface GraphSource

Provides an abstraction of the data being graphed, this way graphs do not need to know anything about the underlying data they are graphing.

Method Summary

double[]	getAcceptableMajorDeltas() Return an array of acceptable major deltas for the vertical axis.
double[]	getAcceptableMinorDeltas() Return an array of acceptable minor deltas for the vertical axis.
Graphable	getGraphable() Get the actual graphable data.
java.lang.String	getName() Return the name of the data.
java.lang.String	getToolTipText(java.lang.Comparable x) Get the tool tip text for the given X value
java.lang.String	getYLabel(double value) Convert the Y value to a label to be displayed in the vertical axis.
