I am plotting a data using contourf but the there is a contour line between the start and end value color even after using the
For example in the attached figure there is a line between dark blue and dark red.
Also, I have tried different colormap but the result is same.

Hmm. I didn't think about that. I don't know that it can be done with contourf().
% make a simple linear ramp that cycles
[xx yy] = meshgrid(1:100);
zz = xx;
zz = circshift(zz,[0 -30]);
% this is what happens with contourf()
[~,h] = contourf(xx,yy,zz,9,'linecolor','none');
% let's try to replicate it with pcolor()
colormap(jet(10)) % set length to number of levels+1
That's about right. I think it makes the colorbar easier to read anyway.
