Hello I am trying to add some point marker on contour plot using the following command.

if true
  hold on;plot(37,12,'.r', 'markersize', 10);
end

and it works fine , but when i use it with contourfm it didnot wrok and the contour squeeze. I attached two figures showing that , the first before I put the marker and the second after I put the marker.

here is my code

if true
 clc
diri='/data/'
filename='msl_t2m.nc'
file=[diri filename]
% ncread is the latest high level matlab commands
ncdisp(file)
lat =ncread(file,'latitude')
long =ncread(file,'longitude')
time =ncread(file,'time')
msl = ncread(file,'msl',... 
  [1 1 1],[length(long) length(lat) length(time)],[1 1  1]);
msl=msl./100.;
fprintf('%f     %f     %f\n',min(msl(:)),max(msl(:)),mean(msl(:)))
%%plotting the data
%contourf(long,lat,msl(:,:,100)');
%colorbar
%%adding map 
latlim = [-90 90];
lonlim = [-180 180];
figure('Color','white')
axesm('eqdcylin','MapLatLimit',latlim,'MapLonLimit',lonlim, ...
 'Frame','on','Grid','on','MeridianLabel','on', ...
 'ParallelLabel','on')
axis off
coast = load('coast.mat');
plotm(coast.lat,coast.long)
gLat = lat(1):-0.75:lat(length(lat));
gLon = long(1):0.75:long(length(long));
[ggLat,ggLon] = meshgrid(gLat,gLon);
contourfm(squeeze(double(gLat)),squeeze(double(gLon)),msl(:,:,100)')
plotm(coast.lat,coast.long)
end
