SUPERIMPOSING and SCALE SHOWING problems Using m_map toolbox in MATLAB r2013b:

1. I need to show the SCALE for wind speed as a legend, or on land.

2. I want to remove the quiver arrows from land, and show land by a colour other than that of quiver. I tried to superimpose image, but only the final image is being saved, looks like the “hold on” & “hold off” commands are not suitable.

The mat files are attached herewith, and codes are as follows:

I = 10; % Interval to plot quiver

%%%Loading mat files of Lon, Lat, mean_U, mean_V
    s = what; %look in current directory
    matfiles=s.mat;
    for a=1:numel(matfiles)
    load(char(matfiles(a)))
    end

m_proj('miller cylindrical','lon',[119 127 ],'lat',[32.1 40]) 
figure;  
h = m_quiver(Lon(1:I:end, 1:I:end), Lat(1:I:end, 1:I:end), mean_U(1:I:end,1:I:end), mean_V(1:I:end, 1:I:end), 1, 'FaceColor','r'); % red arrows
shading flat 
m_gshhs_f('patch','b'); % LAND MASK in blue 
m_gshhs_f('color','k'); % COASTLINE in black
m_grid('box','fancy', 'lines','--');
set(gcf,'PaperPositionMode','auto');
hold on  

% same quiver field with visibility off
set(h, 'Visible', 'off')  
hold off

print( '-dtiff','-r300', 'Mean sea surface wind.tiff');

I am requesting for your kind help.

Where are mat files?

Dear Dr. Siva Srinivas Kolukula,

The 4 mat files (Lat.mat, Lon.mat, mean_U.mat, mean_V.mat) are attached at the end of my query for downloading.

Thanks a lot. Could you help me please solving the problems.

Sincerely yours,

Rashid
