I have a script as follow:
if true
% Set up MOVIE object
vidObj = VideoWriter('Field_adv_diff_2D.avi');
vidObj.Quality = 100;
vidObj.FrameRate = 1;
open(vidObj);
set(gca,'nextplot','replacechildren');
% %%CONTOUR PLOT
% ZLevels = 288:1:300;
Naux = 200;
Minimum = min(min(node_state));
Maximum = max(max(node_state));
levels = Minimum:(max(max(node_state))-min(min(node_state)))/200:Maximum;
% k = 6000;
% Mesh = Mesh_simulator;
Xg = min(Mesh.xy(1,:)):(max(Mesh.xy(1,:))-min(Mesh.xy(1,:)))/Naux:max(Mesh.xy(1,:));
Yg = min(Mesh.xy(2,:)):(max(Mesh.xy(2,:))-min(Mesh.xy(2,:)))/Naux:max(Mesh.xy(2,:));
[XI,YI]=meshgrid(Xg,Yg);
ZI = zeros(length(XI),length(YI));
% for k = (time_sim/4):(time_sim/4):time_sim
for k = [source(4)+1 100:100:source(5)]
for ii=1:size(Mesh.ele,2)
xx = [Mesh.xy(1, Mesh.ele(1,ii)) Mesh.xy(1, Mesh.ele(2,ii)) Mesh.xy(1, Mesh.ele(3,ii))];
yy = [Mesh.xy(2, Mesh.ele(1,ii)) Mesh.xy(2, Mesh.ele(2,ii)) Mesh.xy(2, Mesh.ele(3,ii))];
IN = inpolygon(XI, YI, xx, yy);
% ZI(IN) = (node_state(Mesh.ele(2,ii),k) + node_state(Mesh.ele(3,ii),k) + node_state(Mesh.ele(4,ii),k)) / 3;
% oppure:
points = find(IN);
for i = 1:length(points)
N(i,:) = Get_shapeN_2D_DIFFUSION (Mesh,ii,[XI(points(i)) YI(points(i))]);
ZI(points(i)) = N(i,:)*[node_state(Mesh.ele(1,ii),k); node_state(Mesh.ele(2,ii),k); node_state(Mesh.ele(3,ii),k)];
end
end
figure;
contourf(XI,YI,ZI,levels,'LineStyle','none','LineColor',[0 0 0]);
% colorbar();
caxis([Minimum Maximum])
% colormap(jet)
colormap(gray)
map = colormap;
cmap = flipud(map);
colormap(cmap);
% hold on
% plot(sensor(1,:),sensor(2,:),'ow');
% hold off
title(sprintf('Field map at step %d %f sec)',k));
drawnow('expose');
axis equal;
currFrame = getframe(gcf);
writeVideo(vidObj,currFrame);
end
close(vidObj);
end
The figures are created with cartesian axis, I need to remove it because I should create a video with them.
Someone could help me?
Many thanks

Try this command:
set(gca,'xtick',[])

I like it! It removes the axis but not the blank white background!

Just use the following command:
axis off
