I am mounting a graph, but I need to display the data of a field that is "String", however it only receive integer.
Someone there has been there?
tempo.set(u.formataData(treinos.get(i).getDataTreino()),
u.formataHoraComSegundos(treinos.get(i).getTempoRealizado()));
How is the graph you want to do? Can you show an example using the data you have? Also post the code where this data is.
