Please help me to fix this code. I have 3 sets of data, radius,CA, CPTOT, iam trying to plot contours of CPTOT w.r.t radius and CA along x-axis and y-axis. I have attached txt file for reading y and z values.

load new.txt;

x= linspace(24.94,27.30,264);

>> xmin = min(x(:));

>> xmax = max(x(:));

>> y = a(:,1);

>> z = a(:,2);

>> ymin = min(y(:));

>> ymax = max(y(:));

zmin = min(z(:))

zmax = max(z(:));

ini = 24.94;

last = 27.3;

samples = 264;

>> k=(last-ini)/(samples-1);

[xi,yi]=meshgrid(0:k:xmax,0:k:ymax);

>> zi=griddata(x,y,z,xi,yi);

contour(zi)

What difficulty are you having? Are you getting an error message? Are ou getting a different output than you expect?

Iam not getting contours on my figure window
