i originaly wanted to use an array, but i didnt know how to change the values of the array as they were read from serial... wow im stupid, heh i see how i could do it now.

i now have "int[] JoyData = new int[7];" at the beginning of the code where "ArrayList JoyData = new ArrayList();" was

            //Handle data recieved; something like: 1023,1023,1023,1,1,0,1,      
            string[] split = RxString.Split(new Char[] { ',' });

            int cntwrite=0; 
            foreach (string s in split)
            {
                if (s.Trim() != "")
                {
                    int c = Int32.Parse(s);
                    JoyData[cntwrite]=c; //adds each new value split(s) from SerRead string to JoyData array
                    Console.WriteLine("split #s:");
                    Console.WriteLine(c);
                    ++cntwrite;
                    if(cntwrite >7) //reset cntwrite for next time serial data is recieved
                    {
                    cntwrite=0;
                    }
                }
            }

but now when i try to use

int y=JoyData[2] * 512 / 1023 + 0;
            int x=Joydata[1] * 512 / 1023 + 0;

for the graph in "public Form1()" i get "JoyData doesnt exsist in this context". i thought declaring the JoyData array in the class would fix it, but the error only happens when i use "int y=JoyData[0]"(trying to access first number stored in array), but if i use "int y=JoyData[3]" it doesn't give me an error. arrays start at 0 so why does this happen?

ok thats really weird, now it works....
