float [] pt1x = {0.580f, 0.680f, 0.780f}; 
float [] pt1y = {1.128f, 1.228f, 1.328f}; 

foreach (float xpt in pt1x) {
   System.Console.WriteLine("xpt = " + xpt);
       foreach (float ypt in pt1y) {
        System.Console.WriteLine("ypt = " + ypt);
      }  
}

------my output:
xpt = 0.58
ypt = 1.128
ypt = 1.228
ypt = 1.328
xpt = 0.68
ypt = 1.128
ypt = 1.228
ypt = 1.328
xpt = 0.78
ypt = 1.128
ypt = 1.228
ypt = 1.328

// accept "angle" from the "public float myangle" getter but it does not. So it only draws // one 30 degree hard coded  line.  I desire the line to be incremented around in 10
// degree steps sort of like the second hands of a clock.
