How to plot the figure in LT?

Hi All,

I have x and y column vector of data. x is universal time starts from 0-24. I want to plot local time of figure 0-24 LT. The LT=UT+7

I wrote a code like this but it does not work.

x=[0;1;2;3;4;5;6;7;8;9;10;11;12;13;14;15;16;17;18;19;20;21;22;23;24]; 
y=[0.2;0.3;0.4;0.2;0.7;0.4;0.6;0.3;0.2;0.4;0.2;0.4;0.6;0.2;0.4;0.5;0.7;0.2;0.3;0.2;0.6;0.4;0.2;0.3;0.2];
if  (0<=x<=17)
        x=x+7;
     else 
     x=x-17; 
 end

Would you please help me to correct it?

What is y vector ? Are they some data at those times ?

Y vector is not the same as X vector. Yes they are some data at those times.

x=[0;1;2;3;4;5;6;7;8;9;10;11;12;13;14;15;16;17;18;19;20;21;22;23;24]; 
y=[0.2;0.3;0.4;0.2;0.7;0.4;0.6;0.3;0.2;0.4;0.2;0.4;0.6;0.2;0.4;0.5;0.7;0.2;0.3;0.2;0.6;0.4;0.2;0.3;0.2];
for k = 1:length(x) 
if  x(k)>0 & x(k)<=17
      x(k)=x(k)+7; 
else 
      x(k)=x(k)-17; 
end
end 
plot(x)
