Hi Peter,

I have to crate a simple line graph chart but the line has to change colours -green, amber, red according to a different range of values. Any example that I can look at or any help will be appreciated as always

so far I got this but obviously it does not work

double[] DataGreen = new Double[data0Y.Length];
               double[] DataYellow = new Double[data0Y.Length];
               double[] DataRed = new Double[data0Y.Length] ;

               if (data0Y.Length > 0)
               {
                  for (int i = 0; i == data0Y.Length - 1; i++)
                  {
                     DataGreen[i] = Chart.NoValue;
                     DataYellow[i] = Chart.NoValue;
                     DataRed[i] = Chart.NoValue;
                  }

                  for (int i = 0; i <= data0Y.Length - 1; i++)
                  {
                     if(data0Y[i]>=0 && data0Y[1]<=10)
                     {
                        DataGreen[i]=data0Y[i];
                     }

                     else if (data0Y[i] >= 11 && data0Y[1] <= 20)
                     {
                        DataYellow[i] = data0Y[i];
                     }
                     else
                     {
                        DataRed[i] = data0Y[i];
                     }
                  }
               }

                layer0 = c.addLineLayer2();
               layer0.addDataSet(DataGreen, 0x187E03).setDataSymbol(Chart.GlassSphere2Shape, 11);
               layer0.addDataSet(DataYellow, 0xECD36F).setDataSymbol(Chart.GlassSphere2Shape, 11);
               layer0.addDataSet(DataRed, 0xff0000, y0Title).setDataSymbol(Chart.GlassSphere2Shape, 11);

               layer0.setXData(data0X);
               layer0.setLineWidth(3);

Peter do not worry about this as my colleague Brian find a solution; he also posted on this forum and he is asking about some comments on his solution
