Method Detail

addDiagonal

public static void addDiagonal(org.jfree.data.xy.DefaultXYDataset dataset,
                               double min,
                               double max)

Adds a diagonal to the dataset.

Parameters:

dataset - the dataset to add the diagonal to

min - the minimum Y

max - the maximum Y

getDiagonalIndex

public static int getDiagonalIndex(org.jfree.data.general.SeriesDataset dataset)

Returns the index of the series represnting a diagonal.

Parameters:

dataset - the dataset

Returns:

the 0-based index, -1 if none present

hasDiagonal

public static boolean hasDiagonal(org.jfree.data.general.SeriesDataset dataset)

Checks the dataset whether a diagonal series is present.

Parameters:

dataset - the dataset to check

Returns:

true if present

isDiagonal

public static boolean isDiagonal(org.jfree.data.general.SeriesDataset dataset,
                                 int index)

Checks whether the specified series represents a diagonal.

Parameters:

dataset - the dataset to check

index - the index of the series to check

Returns:

true if diagonal

applyShape

public static void applyShape(org.jfree.chart.plot.XYPlot plot,
                              Shape shape)

Sets the shape for all series except the diagonal.

Parameters:

plot - the plot to update

shape - the shape to set, ignored if null

applyColor

public static void applyColor(org.jfree.chart.plot.XYPlot plot,
                              Color plotColor,
                              Color diagonalColor,
                              ColorProvider colorProvider)

Applies the color to the series.

Parameters:

plot - the plot to update

plotColor - the plot color to use if just one series (or series with diagonal), ignored if null

diagonalColor - the color for the diagonal (if present)

colorProvider - the color provider to get the colors from (is not reset before calling "next()")
