Hello and thank you very much for the reply, My list of data is very large and it gives me some errors, I was thinking to reduce the number of points and put some constraints to the list terms so that I could have this work. Should I use Select or Cases? (But I dont know how to do it) I copied here the first terms: data= {{1.1795*10^-12, 0.}, {1.1795*10^-12, 0.000011918}, {1., \ 0.0000276853}, {1., 0.000027194}, {1., 0.0000242474}, {1., \ 0.0000267025}, {1., 0.0000281765}, {1., 0.0000276853}, {1., \ 0.000031607}, {1., 0.0000276853}, {1., 0.000027194}, {2., \ 0.0000262109}, {2., 0.0000232628}, {2., 0.0000379602}, {2., \ 0.0000355202}, {2., 0.0000311167}, {2., 0.000035031}, {2., \ 0.0000306263}, {2., 0.0000374716}, {2., 0.0000360052}, {3., \ 0.0000306263}, {3., 0.0000203098}, {3., 0.0000355202}, {3., \ 0.0000384486}} Thanks again.
