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

在 MATLAB Online 中打开

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
