I have code for figure with superimposition of temperature image and quiver plot in loop.

But it image shifts every loop if side arrows exceed length of 1 pixel. How i can lock image or scale arrows?

[x,y]=meshgrid(1:1:31,1:1:38);
k=4997;
cnt=0;
heat_conductivity=28;
d=4;
for i=1:k
    [dTdx,dTdy] = gradient(V(:,:,i));
    u(:,:,i) = -heat_conductivity*dTdx;
    v(:,:,i) = -heat_conductivity*dTdy;
    
end
f=figure('Renderer', 'painters', 'Position', [10 10 600 620]);
ax=gca;
ax.XLim = [1 38];
ax.YLim = [1 31];
%f.WindowState='maximized';
for i=1:k
    %figure
    imagesc(V(:,:,i));
    axis tight
    hold on
   
    q=quiver(x,y,v(:,:,i),u(:,:,i))
    %q.AutoScale='on';
    q.AutoScaleFactor=0.9;
    q.ShowArrowHead='on';
    %q.MaxHeadSize= 1;
    q.AlignVertexCenters='on';
    q.LineWidth=0.5;
    q.MaxHeadSize=1;
    q.Color='black';
    %axis tight
    colormap jet
    colorbar
    caxis([26 35])
    cnt=i;
    title(cnt);
    
    pause (0.1)
    clf;
end

Problem was with quiver itself and arrows. Thats why adding X,Y limits after quiver function helped. Hope it will be helpful for others

f=figure('Renderer', 'painters', 'Position', [10 10 600 620]);
% ax=gca;
% ax.XLimMode='manual';
% ax.YLimMode='manual';
% ax.XLim = [1 38];
% ax.YLim = [1 31];
%f.WindowState='maximized';
for i=1:k
    %figure
    imagesc(V(:,:,i));
    
    axis tight
    hold on
   
    q=quiver(x,y,v(:,:,i),u(:,:,i))
    %q.AutoScale='on';
    q.AutoScaleFactor=0.9;
    q.ShowArrowHead='on';
    %q.MaxHeadSize= 1;
    q.AlignVertexCenters='on';
    q.LineWidth=0.5;
    q.MaxHeadSize=1;
    q.Color='black';
    %axis tight
    xlim manual
    ylim manual
    axis ([1 31 1 38 ])
    colormap jet
    colorbar
    caxis([26 35])
    cnt=i;
    title(cnt);
    
    pause (0.1)
    clf;
end
