how to correctly spaced the X and Yticklabel?

Hi, this is my code:

vec=[-180 -36 0 36 180]     
for i=1:3
         figure(1)
  subplot(1,3,i)
  if i==1
  contourf(vec,vec,nzro_mean1)
  elseif i==2
      contourf(vec,vec,nzro_mean2)
  elseif i==3
      contourf(vec,vec,nzro_mean3)
  end
  axis square
  xt=get(gca, 'Xtick');
  xtv=linspace(min(xt), max(xt), numel(vec));
  yt=get(gca, 'Ytick')
  ytv=linspace(min(yt), max(yt), numel(vec));
  set(gca, 'XTick',xtv, 'XTicklabel',{vec}, 'YTick',ytv, 'YTicklabel', {vec})
  axis equal
  title(['Especie ',num2str(i)])
  colorbar('southoutside')

       end

but the Xticklabels are spaced differently than Yticklabel, I don't understand, everything I tried just make it worse or the same... Xticklabel is wrongly spaced and the farest I came is to get Yticklabel as wrong as Xticklabel.

Your code doesn't run. What is nzro_mean1, etc.? And you forgot to include a screenshot so we don't know what you're talking about. Please do so and indicate which spaces or spacings or separations of what from what you're talking about. In the meantime, check out the functions xticks(), yticks(), and axis() and their input parameters.
