Hi

read the data in i.e data set and do like below

it will give you like GW@00000
same for other values in loop and add them in class properpty like

for each(--- your file read file data)
{
project obj= new project()
obj.ProjectName= ToString.Trim().Substring(0, 10);
obj...
obj...
}

you need to create a logic to break string and after that create a class assign these values to that and convert ot json. it will easy to plot a graph

this is file read

System.IO.StreamReader file = new System.IO.StreamReader("D:\\praveen\\123.txt");
while ((line = file.ReadLine()) != null)
{
System.Console.WriteLine(line);
counter++;
}
file.Close();

for sub string take values from the line
string filename = "D:\\praveen\\123.txt";
using (StreamReader r = new StreamReader(filename))
{
string s = string.Empty;
int i = 0;
while ((i = r.Read()) != -1)
{
Char c = Convert.ToChar(i);
if (Char.IsDigit(c) || Char.IsLetter(c))
{
s = s + c;
}
else
{
if (s.Trim() != string.Empty)
Console.WriteLine(s);
s = string.Empty;

Share more information that which graph you are using and how you are reading consuming that data.
