I am having trouble plot the data dynamically,my goal is to plot data after checking a certain test of 14 days if I entered that condition loop I would like to execute a rectangle between the 1st day and the 14th day. when I enter that last if loop I already have a xfist,xlast,y first y last. so I can draw a rectangle between them. And then when I pass the 14 days test again I would like to add to the existing plot another rectangle.
Here is my code so far.
The plot lines don't plot anything.
j=1;
while(j<72)
boom=true;
if a13(j)~= b8(j)|| a13(j)>1.1*(b8(j))&& a13(j)<0.9*(b8(j))
elseif a13(j)~=c5(j)|| a13(j)<0.9*(c5(j))&&a13(j)<0.9*(c5(j))
boom=false;
end
Xfirst=[];
Yfirst=[];
Xlast=[];
Ylast=[];
Yfirst=a13(j);
Xfirst=datetime(Date(j));
for i=j+1 :j+14
if a13(i)~= b8(i)|| a13(i)>1.1*(b8(i))&& a13(i)<0.9*(b8(i))
elseif a13(i)~= c5(i) || a13(i)<0.9*(c5(i)) && a13(i)>1.1*(c5(j))
j=i;
boom=false;
break;
end
end
if(boom==true)
Ylast=a13(j+14);
Xlast=New_Date(j+14);
figure (1)
plot(Xfirst,Yfirst)
hold on
plot(Xlast,Ylast)
end
j=j+1;
end
use drawnow
inside the loop:
j=1;
while(j<72)
boom=true;
if a13(j)~= b8(j)|| a13(j)>1.1*(b8(j))&& a13(j)<0.9*(b8(j))
elseif a13(j)~=c5(j)|| a13(j)<0.9*(c5(j))&&a13(j)<0.9*(c5(j))
boom=false;
end

Yfirst=[];
Xlast=[];
Ylast=[];
Yfirst=a13(j);
Xfirst=datetime(Date(j));
for i=j+1 :j+14
if a13(i)~= b8(i)|| a13(i)>1.1*(b8(i))&& a13(i)<0.9*(b8(i))

j=i;

break;
end
end
if(boom==true)
Ylast=a13(j+14);
Xlast=New_Date(j+14);
figure (1)
plot(Xfirst,Yfirst)
hold on
plot(Xlast,Ylast)
drawnow; % To force figure to update
pause(0.2); % to allow time for it to render
end
j=j+1;
end
drawnow
