Finally, perhaps the most informative figure of all in figure 3: simple scatter plots and histograms of all variables have been derived. The machine cell information is coded as an eleventh variable: m1, m2…m10 for machines. Original data points are in the upper triangle, map prototype values on the lower triangle, and histograms on the diagonal: 
black for the data set and red for the map prototype values. The color coding of the data samples has been copied from the map (from the BMU of each sample). The variable values have been denormalized. The clear two black blocks inside red map prototype indicates the existence of two clusters of the data set. This visualization shows quite a lot of information: distributions of single and pairs of variables both in the data and in the map. If the number of variables was even slightly more, it would require a really big display to be convenient to use. From this visualization we can conform many of the earlier conclusions, for example: 
- there are two clusters: 'Cell1' (blue, green) and 'Cell2' (orange, reds).This is visible in almost any of the subplots.

- m1, m3, m5, m9 have a high linear correlation (see subplots 3, 1 and 5, 1 and 9, 1 and also in 5,3 and 9,3 and 9,5)
- m4, m6, m7, m8 is highly correlated in subplots 6, 4 and 7,4 and 8,4 and 7,6 and 8,6 and 8,7)
- m2 and m10 have a clear linear correlation, but it is slightly different for the two main clusters (in subplots 10,1 and 10,3 and 10,5 and 10,9 and 4,2 and 6,2 and 7,2 and 8,2). The part family formation can be similar way analysed and compared the extraction using the color extraction and hit from PC projection of SOM map (figure2) and matched with the U-matrix. Thus two part family with p3, p4, p5, p6, p7, p8, p9 and p1 ,p2, p10 can be formed processed by two machine cells(m1,m3,m5,m9, m10 and m2, m4, m6, m7, m8) as identified by the proposed method of SOM clustering. These two clusters (Cell1 and Cell2) as derived from all the above discussed visual inspection of SOM map has given rise to two machine-part cells when block diagonal form table 2 has been derived from the original machine-part incidence matrix table 1 after arranging the information of part family processing in machine group.
