TimeIntervalGraphics

public TimeIntervalGraphics(double min,
                            double max)

Create a new TimeIntervalGraphics with the given minimum and maximum times to render intervals later.

Parameters:

min - Minimum time of all intervals

max - Maximum time of all intervals

Method Detail

calculateRange

private void calculateRange()

createTimeIntervalImage

public BufferedImage createTimeIntervalImage(double start,
                                             double end,
                                             int width,
                                             int height)

Creates a time interval graphic representation with default colors. If starts or ends are infinite, they will be normalized to the min or max values range.

Parameters:

start - Start of the interval (must be greater or equal than minimum time)

end - End of the interval (must be lesser or equal than maximum time)

width - Image width

height - Image height

Returns:

Generated image for the interval

createTimeIntervalImage

public BufferedImage createTimeIntervalImage(double start,
                                             double end,
                                             int width,
                                             int height,
                                             Color fill,
                                             Color border)

Creates a time interval graphic representation with the indicated fill and border colors (or null to use default colors). If starts or ends are infinite, they will be normalized to the min or max values range.

Parameters:

start - Start of the interval (must be greater or equal than minimum time)

end - End of the interval (must be lesser or equal than maximum time)

width - Image width

height - Image height

fill - Fill color for the interval

border - Border color for the interval
