setColorInterpolated

public void setColorInterpolated(int index,

setColorRange

public void setColorRange(int firstIndex,
                          int lastIndex,
                          int color1,
                          int color2)

setColorRange

public void setColorRange(int firstIndex,
                          int lastIndex,
                          int color)
