Hello everyone,
I'm trying to do a cumulate of 'DATI_ECM_GIORNALIERI' but the variable doesn't appear.
Then, I only have to plot it (eg Cum_Giul.SMB_mpmm) instead of DATIECMWFgiornalieri.SMB_mpmm, as you can see at the end of the plot.
Thank you very much.

Check for incorrect argument data type or missing argument in call to function 'retime'.

DATIECMWFgiornalieri is a table() object. You cannot retime() a table() object. You need to take that Dtv you created and
Cum_Giu = retime(table2timetable(DATIECMWFgiornalieri, 'RowTimes', DTv), 'daily', @(x)sum(x,'omitnan'))

Cum_Giu = retime(table2timetable(DATIECMWFgiornalieri, 'RowTimes', DTv), 'daily', @(x)sum(x,1,'omitnan'))
CTv = Cum_Giu.Properties.RowTimes;
yyaxis left
plot(CTv, Cum_Giu.SMB_mpmm, 'm', 'DisplayName','ECMWF');
yyaxis right
plot(C,NEW, 'DisplayName','AWS')
Ax = gca;
Ax.YAxis(2).Color = 'm';
