I need help to plot 2D contours as shown in the figure for mutiple files. I am attaching my code and data files for your reference. I am unable to plot it due to some mistake in the code.
navg = 11;
filenames = cell(navg,1);
for i = 1:navg
filenames = sprintf('queen2_test_%d.dat', i);
mydata{i}=importdata(filenames);
% writematrix(avg_mat{i}, filenames{i});
R = mydata{i}(:,1);%X
C = mydata{i}(:,2);%Y
F = mydata{i}(:,7);%F(X,Y)
figure
contour(R,C,repmat(F,1,numel(C))');
grid on;
end
saveas(gcf,figure,'.png']);

Run the attached code with the files you provided
navg = 11;
filenames = cell(navg,1);
for i = 1:navg
filenames = sprintf('queen2_test_%d.dat', i);
mydata{i}=importdata(filenames);
% writematrix(avg_mat{i}, filenames{i});
R = mydata{i}(:,1);%X
C = mydata{i}(:,2);%Y
F = mydata{i}(:,7);%F(X,Y)
rg = linspace(min(R), max(R), 100);
cg = linspace(min(C), max(C), 100);
[Rg, Cg] = meshgrid(rg, cg);
Fg = griddata(R, C, F, Rg, Cg);
figure
ax = axes();
ax.YDir = 'reverse';
hold on;
contourf(Rg,Cg,Fg);
ax.XAxisLocation = 'top';
cb = colorbar('Location', 'south');
cb.Position(2) = cb.Position(2)-0.11;
grid on;
saveas(gcf,filenames(1:end-4),'png');
delete(gcf);
end

hi ameer,
I want to label the colur bar as shown in the figure1.
my current code is labelling beside as shown in the figure below instead of labelling on the top as shown in the above figure1 .
h = colorbar;
xlabel(h, 'ω')
Kindly suggest a code.

I made the code to change the postion. Thanks.
pos = get(h,'Position');
h.Label.Position = [2 30]; % to change its position
h.Label.Rotation = 0; % to rotate the text
