ok

u can do in this way 

first stored ur value in one strin say s1

then create string array s2 

say 

dim s2 as string[]=s1.split( ',' )

now use for loop to attach this values to graph in this way

for i =0 to s2.length

chart.Data.Add(New WebChart.ChartPoint( i+1&"position value", s2[i]))

next
