Hello everyone,
Im trying to make a loop of a specific variable using pcolor, but I don't want to add the map area in every loop stage. There's is any way to permanently keep the map area and only change the pcolor variable, thanks for your time.
for i = 1 :8*4;
pcolor(lon,lat,u(:,:,i));
% hold on, fillseg(map(:,1),map(:,2)),hold off; %map of the coastal area
colormap c2h,caxis([-0.5 0.5]);
title(num2str(gtime(i,4)));
pause(.1);
end

If you take care of the handle you get from pcolor you should be able to do something like this:
H = pcolor(...)
% Initial plottery
phMap = fillseg(map(:,1),map(:,2)); %map of the coastal area
hold on
colormap(c2h)
%
for i = 1 :8*4;
pch = pcolor(lon,lat,u(:,:,i));
caxis([-0.5 0.5]);
title(num2str(gtime(i,4)));
pause(.1);
delete(pch)
end
If you want the map on top of the pcolor plot, one easy QD-fix is to replace pcolor with something like:
pch = surf(lon,lat,-1*ones(size(u(:,:,i))),u(:,:,i));view(0,90)
