Contour Plot Edge Issue

I am attempting to plot temperature at different locations in an x-z crosssection. For some reason the contour plot seems to have issues handling the edge of the plot where the contour lines end. Here is a picture of what it looks like when I try to plot just one contour line:

Anyone know how to fix this issue?

Where is the code?

Sorry here it is:

matrix contains the x,z, and temperature values

XD = matrix(:,1);
ZD = matrix(:,2);
tempD = matrix(:,3);

[X,Z] = meshgrid(XD,ZD);
B=griddata(XD,ZD,tempD,X,Z);
contour(X,Z,B,[1673.15,1673.15])

Where is data?

Its a little complicated which is why i did not include it, but here is how I create the matrix:

matrix = [];
for val = 1:length(xarray)
    for val2 =1:length(zarray)
        x = xarray(val);
        w = x-v*tPrime;
        xDLess = v*w/(2*a);
        z = zarray(val2);
        y = 0;
        yDLess = v*y/(2*a); % dimensionless y distance
        zDLess = v*z/(2*a); % dimensionless z distance
        upper = v^2*tPrime/(2*a);
        theta = n/(2*pi)^(1/2)*integral(@(tau)fun(tau, xDLess, yDLess, zDLess), 0, upper);
        realT = theta*(Tc-To)+To;
   
        alpha = [x -1*z realT];
        matrix = [matrix;alpha];
    end
end

How am i supposed to run this code without these?
