Hello, I tried with log of the data, but its not that good. The problem is with the missing datas, zero datas. And Ansley, I also tried your suggestion. The conset works with lines but don't with colors. But i attach the file. I think the lines+filling colors between them should work, but till do not know how. I get many errors after that. Peter
