Hello eveyone, the following relies on the following Exchange file: downloaded GDP data for selected countires:

startDate = strcat('1996-01-01');
endDate = strcat('2017-12-31');
[calDate, GDPdeu]=fred2read('DEUGDPNQDSMEI',startDate,endDate);
[~, GDPfra]=fred2read('FRAGDPNQDSMEI',startDate,endDate);
[~, GDPita]=fred2read('ITAGDPNQDSMEI',startDate,endDate);
[~, GDPesp]=fred2read('ESPGDPNQDSMEI',startDate,endDate);
[~, GDPaut]=fred2read('AUTGDPNQDSMEI',startDate,endDate);
[~, GDPbel]=fred2read('BELGDPNQDSMEI',startDate,endDate);
[~, GDPfin]=fred2read('FINGDPNQDSMEI',startDate,endDate);
[~, GDPirl]=fred2read('IRLGDPNQDSMEI',startDate,endDate);
[~, GDPlux]=fred2read('LUXGDPNQDSMEI',startDate,endDate);
[~, GDPnld]=fred2read('NLDGDPNQDSMEI',startDate,endDate);
[~, GDPprt]=fred2read('PRTGDPNQDSMEI',startDate,endDate);
for i=0:21
   calDateYear(i+1) = calDate(4*i+2);
   GDPdeuYear(i+1) = 1000000* (GDPdeu(4*i+1)+GDPdeu(4*i+2)+GDPdeu(4*i+3)+GDPdeu(4*i+4));
   GDPitaYear(i+1) = 1000000* (GDPita(4*i+1)+GDPita(4*i+2)+GDPita(4*i+3)+GDPita(4*i+4));
   GDPfraYear(i+1) = 1000000* (GDPfra(4*i+1)+GDPfra(4*i+2)+GDPfra(4*i+3)+GDPfra(4*i+4));
   GDPespYear(i+1) = 1000000* (GDPesp(4*i+1)+GDPesp(4*i+2)+GDPesp(4*i+3)+GDPesp(4*i+4));
   GDPautYear(i+1) = 1000000* (GDPaut(4*i+1)+GDPaut(4*i+2)+GDPaut(4*i+3)+GDPaut(4*i+4));
   GDPbelYear(i+1) = 1000000* (GDPbel(4*i+1)+GDPbel(4*i+2)+GDPbel(4*i+3)+GDPbel(4*i+4));
   GDPfinYear(i+1) = 1000000* (GDPfin(4*i+1)+GDPfin(4*i+2)+GDPfin(4*i+3)+GDPfin(4*i+4));
   GDPirlYear(i+1) = 1000000* (GDPirl(4*i+1)+GDPirl(4*i+2)+GDPirl(4*i+3)+GDPirl(4*i+4));
   GDPluxYear(i+1) = 1000000* (GDPlux(4*i+1)+GDPlux(4*i+2)+GDPlux(4*i+3)+GDPlux(4*i+4));
   GDPnldYear(i+1) = 1000000* (GDPnld(4*i+1)+GDPnld(4*i+2)+GDPnld(4*i+3)+GDPnld(4*i+4));
   GDPprtYear(i+1) = 1000000* (GDPprt(4*i+1)+GDPprt(4*i+2)+GDPprt(4*i+3)+GDPprt(4*i+4));
end

Basically, I created new vairable showing yearly rather than quarterly GDP.

Now I want to show the shares of each country's GDP graphically, compared to the overall amunt of the GDP. What i would like to do is to plot GDPdeuYear(i+1), GDPdeuYear(i+1) + GDPitaYear(i+1), ... In order to "add up* the plot of every country. But I am not very successfull in doing it. I'm also aware that there should be a more elegant way to do it. Additionaly, it would be nice to have a (differently) colored area under each line to make comparison possible. Can anyone help me?

@Jan by that part I mean:

If I just plot every country's GDP the upper curve shows the time-series for the country that has the highest GDP. Instead, the upper curve should diplay the sum of all GDPs. Here is an example. Schermata 2018-12-03 alle 19.11.47.png
