My input

"ID"	"Label"	"*Stype*"	"Ntype"	"Stype_No"	"*log*"
"S1"	"xxx"	"A/A"	1	6	2.8
"S1"	"xxx"	"A/G"	2	2	3
"S1"	"xxx"	"G/G"	3	1	4
"S2"	"yyy"	"A/A"	1	1	6.8
"S2"	"yyy"	"A/G"	2	2	7
"S2"	"yyy"	"G/G"	3	6	7.4
"S2"	"yyy"	"NULL"	"null"	"null"	8
"S3"	"zzz"	"A/A"	1	3	12
"S3"	"zzz"	"A/G"	2	3	14
"S3"	"zzz"	"G/G"	3	3	16
"S3"	"zzz"	"NULL"	"null"	"null"	18
"S3"	"zzz"	"NULL"	"null"	"null"	20




I would like to draw a single scatter plot for every ID (S1 -plot and 
S2-Plot....)by using *Stype* as X axis and *log* as Y-axis with a header 
"D_Scatterplot".
For example S1-Plot looks like this
X-axis consider Stype A/A=1   A/G=2   G/G=3 and their Stype_No 
(6,2,1)means A/A  i.e, 1 repeated 6 times with log values 2.8,3 and 4 
and A/G i.e. 2 repeated 2 times and G/G i.e. 3 1 time with the same log 
values. simply it looks like this

1 	2 	3 	2.8
1 	2 	
	3
1 	
	
	4
1 	
	
	
1 	
	
	
1 	
	
	



Y-axis    

Label_     6 |
log           5 |
                4 |   ***
                3 |   ** *        *
                2 |   ** *        *         *
                1 |
                0 |______________________
                       A/A   A/G   G/G           
                                                       
                               ID*

Thanx n advance
