data_TT = timetable(data.dt,data{:,4});
data_monthly_mean= retime(data_TT(data_TT.Time.Year==choice_year,:),'monthly','mean');
data_monthly_max = retime(data_TT(data_TT.Time.Year==choice_year,:),'monthly','max');
data_monthly_min = retime(data_TT(data_TT.Time.Year==choice_year,:),'monthly','min');
figure(1)
plot(data_monthly_mean.Var1)
hold on
plot(data_monthly_max.Var1)
plot(data_monthly_min.Var1)
hold off
