MATLAB: How to plot it

graphplot

I have the following code. I want a plot between var1 vs e where var1 is along x-axis and ranges from 0 to 10.
th=pi/180;
b=[var1;7;50*th;85*th];
u=[2;7;50*th;85*th]; 
[~,C]=size(b);
P=C/2;
M=2*C;
xo=zeros(1,M);
for k=1:M 
    for i=1:P 
        xo(1,k)=xo(1,k)+u(i)*exp(-1i*(k-1)*pi*cos(u(P+i))); 
    end 
end
xe=zeros(1,M);
for k=1:M
        for i=1:P
            xe(1,k)=xe(1,k)+b(i)*exp(-1i*(k-1)*pi*cos(b(P+i)));
        end 
end 
abc=0.0;
for m1=1:M
  abc=abc+(abs(xo(1,m1)-xe(1,m1))).^2;  
end 
abc=abc/M; 
e=abc

More like this perhaps:
th=pi/180;
u=[2;7;50*th;85*th]; 
var1 = 0:0.5:10;                %%%%%%%%%%%%%%%%%%%%%




for j = 1:numel(var1)           %%%%%%%%%%%%%%%%%%%%%
    b=[var1(j);7;50*th;85*th];  %%%%%%%%%%%%%%%%%%%%%
    C=numel(b);                 %%%%%%%%%%%%%%%%%%%%%
    P=C/2;
    M=2*C;
    xo=zeros(1,M);
    for k=1:M 
        for i=1:P 
            xo(1,k)=xo(1,k)+u(i)*exp(-1i*(k-1)*pi*cos(u(P+i))); 
        end 
    end
    xe=zeros(1,M);
    for k=1:M
            for i=1:P
                xe(1,k)=xe(1,k)+b(i)*exp(-1i*(k-1)*pi*cos(b(P+i)));
            end 
    end 
    abc=0.0;
    for m1=1:M
      abc=abc+(abs(xo(1,m1)-xe(1,m1))).^2;  
    end 
    abc=abc/M; 
    e(j)=abc;                   %%%%%%%%%%%%%%%%%%%%%
end
plot(var1,e),grid
xlabel('var1'),ylabel('e')
