The method and system includes a controllable display comprising a matrix of areas each corresponding to one type of the plurality of flaws and each capable of displaying any one of a first, second and third color. Signals corresponding to different detected flaws are received for controlling the display to initially display all of the areas in the first color, to individually change the color of an area to the second color in response to the detection of a first preselected threshold value of flaws of a type corresponding to the area and to individually change the color of an area from the second color to the third color in response to the detection of a second preselected threshold value of corresponding type flaws, which is higher than the first preselected threshold value.
