Method Detail

color

public static long color(io.airlift.slice.Slice color)

rgb

public static long rgb(long red,
                       long green,
                       long blue)

color

public static long color(double value,
                         double low,
                         double high,
                         long lowColor,
                         long highColor)

Interpolate a color between lowColor and highColor based the provided value

The value is truncated to the range [low, high] if it's outside. Color must be a valid rgb value of the form #rgb

color

public static long color(double fraction,
                         long lowColor,
                         long highColor)

Interpolate a color between lowColor and highColor based on the provided value

The value is truncated to the range [0, 1] if necessary Color must be a valid rgb value of the form #rgb

render

public static io.airlift.slice.Slice render(io.airlift.slice.Slice value,
                                            long color)

render

public static io.airlift.slice.Slice render(long value,
                                            long color)

render

public static io.airlift.slice.Slice render(double value,
                                            long color)

render

public static io.airlift.slice.Slice render(boolean value)

bar

public static io.airlift.slice.Slice bar(double percent,
                                         long width)

bar

public static io.airlift.slice.Slice bar(double percent,
                                         long width,
                                         long lowColor,
                                         long highColor)
