Hello,
i am trying to plot the two graphs and fill the area between the two graphs but only if Ventricle < Atrium. I already could fill the are but i want to cut the connection between the areas. Any ideas how I can seperat them?
%Import Data
Druck = readtable("Part1.txt","Delimiter",'space',"DecimalSeparator",",","ReadVariableNames",false);
TabDruck = Druck(:,4:5);
TabDruck.Properties.VariableNames{1} = 'LV';
TabDruck.Properties.VariableNames{2} = 'LA';
Ventricle = (TabDruck{:,"LV"})';
Atrium = (TabDruck{:,"LA"})';
time = 1:length(Ventricle);
condition = (Ventricle < Atrium)';
tcon = time(condition);
Vcon = Ventricle(condition);
Acon = Atrium(condition);
tLiegBed2 = [tcon, fliplr(tcon)];
inBetween = [Vcon, fliplr(Acon)];
%plot
plot(time,Ventricle,'r')
hold on
plot(time,Atrium,'g')
fill(tLiegBed2, inBetween, 'g','Linestyle','none');
hold off

Try surf
x = [time; time];
y = [Ventricle; min([Ventricle;Atrium])];
surf(x,y,x*0,'edgecolor','none','facecolor','r')

Thank you very much. I was looking for the little area so I change your code a little bit.
x = [time; time];
y = [Atrium; min([Ventricle;Atrium])];
surf(x,y,x*0,'edgecolor','none','facecolor','r')
