how can I plot a degree variable, a scalar and a date

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.

[KSSV]

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)

mmm I think I explained wrong. It is all the information of a month, each day has 48 cells so day 1 goes from cell 1 to 48, day 2 from 49 to 96 so in the end we've got 30 different plots. And could it be as a line not every new data from the beginning?

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
