CartesianTablePlotData

public CartesianTablePlotData(StarTable table,
                              String[] setExprs,
                              String[] setNames,

                       throws gnu.jel.CompilationException

Constructor.

Parameters:

table - table this data is based on

setExprs - nset-element array of JEL boolean expressions for subset inclusion criteria

setNames - nset-element array of subset names

setStyles - nset-element array of subset plot styles

labelExpr - JEL String expression for text label

coordExprs - ndim-element array of JEL numeric expressions for coords (numeric = widenable to double)

errExprs - array of expression pairs giving error lower and/or upper bounds

Throws:

gnu.jel.CompilationException
