I have a matrix SH=721X1440
I want to make a spatial map with that. lat=721x1 , lon=1440x1, time = 1044624. I attached lat matrix as lat1 and lon matrix as lon1.
index=find((lon1>180));
new_lon=lon1(index,1)-360;
new_lon1=([new_lon;lon1(1:721)]);
% for l=1:12
% disp(l)
l=1;
flayer=SH(l,:,:);
reshape_one=reshape(SH(l,:,:),[721 1440]);
[LON,LAT] = meshgrid(new_lon1,lat1);
shift_sh=circshift(reshape_one,720,2);
figure1 = figure;
load coast;
axes1 = axes('Parent',figure1,'FontSize',14,'DataAspectRatio',[1 1 1]);
box(axes1,'on');
grid(axes1,'on');
axes1.GridColor = [0, 0, 0];
xlabel(['Longitude (',char(176),')'],'FontSize',18,'FontName','Arial','FontWeight','bold');
ylabel(['Latitude (',char(176),')'],'FontSize',18,'FontName','Arial','FontWeight','bold');
set(gca,'XLim',[-180 180]);
set(gca,'YLim',[-90 90]);
set(gca,'XTick',-180:30:180);
set(gca,'YTick',-90:30:90);
hold on
xlim([-180 180]);
ylim([-90 90]);
h=pcolor(LON,LAT,shift_sh);
h.EdgeColor='none';
hold on
colormap jet
hold on
h1=geoshow(lat, long, 'color', 'black','linewidth', 2);
% colorbar;
c=colorbar;

Let X, Y, Z be your data. Where X is m*n, Y is m*n and Z is m*n*p matrix.
for i = 1:p
pcolor(X,Y,Z(:,:,i))
drawnow
end
To plot a time series at a point (i,j)
plot(squeeze(Z(i,j))) ;
Also have a look on slice.
