How to plot this line?

Hello everyone,

I should plot line 19 (with years, months and days) but it gives me this error.

And when I try to plot in another way with line 12, not all of the data of lines 19 appear in the graph.

Can anyone help me kindly?

load('GIULIA_MMEQ1.mat');
A=GIULIAMMEQ1.Var4;
B=str2double(A);
NEW= B * 10 * 0.35;
C=GIULIAMMEQ1.Dec1997;%array2table
C=replace(C,"';","");
C=datetime(C,'InputFormat','dd MMM yyyy'); %convert to datetime format
plot(C,NEW) 

load('DATI_ECM_GIORNALIERI');

hold on
plot(datetime(DATIECMWFgiornalieri.Year,1,1),(DATIECMWFgiornalieri.Month,1,1),(DATIECMWFgiornalieri.Days,1,1), DATIECMWFgiornalieri.SMB_mpmm,'m-*', 'DisplayName','ECMWF');

Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

plot(datetime([DATIECMWFgiornalieri.Year, DATIECMWFgiornalieri.Month, DATIECMWFgiornalieri.Days]), DATIECMWFgiornalieri.SMB_mpmm, 'm-*', 'DisplayName','ECMWF');
