Hi, so I got three variables: one gives me the direcction of the wind every half an hour, another one gives me the value of the wind every half an hour and finally one gives me the date of each information. How could I plot it to see the evolution of it every day? I upload the data I used.

load('DataRaval.mat')
load('Direcwind.mat')
load('Velwind.mat')
thedates = datestr(DataRaval) ;
theta = DirecVentRaval ;
W = VelVentRaval ;
u = W.*cosd(theta) ;
v = W.*sind(theta) ;
figure(1)
x = (1:length(u))' ;
y = ones(size(x)) ;
quiver(x,y,u,v) ;
xticklabels(thedates)
figure(2)
plot(x,W)
xticklabels(thedates)

why? The problem I got is to graph the degrees not the days. Look this code, it gives me a plot every day
figure(3)
for k = 1:48:numel(PresionRaval)
nexttile
vend = min(k+48,numel(PresionRaval));
plot(datenum(DataRaval(k:vend,1)),PresionRaval(k:vend,1));
datetick('x','HHPM')
xlabel('Hores'),ylabel('Pressió (hPa)')
title(sprintf('Març %d',floor(k/48)+1))
text(0.05,0.95,sprintf('%.3fhPa',mean(PresionRaval(k:vend,1),'omitnan')),...
'units','normalized','verticalalignment','top')
end
sgtitle('Pressió dies de març')
I want the same but with the direccion given. I read about
