Sir I have done a plotting of soil moisture map for a region and plot its shapefile upon it.My code is

if true
  % code
end 
figure;
axesm('MapProjection','eqdcylin','maplatlimit',[26.0 38.0],'maplonlimit',[70.0 85.0],...'ParallelLabel','on','PlabelMeridian','west','MeridianLabel','on','MLabelParallel','south',...'FontSize',6,'FontWeight','bold','PLineLocation',20,'MLineLocation',20);
latitudes = 26:0.25:38;
longitudes = 70:0.25:85;
[latGrid,lonGrid]=meshgrat(latitudes,longitudes);  
geoshow(latGrid,lonGrid,double(a),'DisplayType','texturemap');
a=ncread('C:\Users\Tanmoyee\Desktop\GFS\datafiles_RH_20Apr_03May16\gdas1.fnl0p25.2016042000.f00.grib2.thakur159756.nc','RH_P0_L103_GLL0');
colormap(flipud(hot(21)));  
chandle = colorbar('Location','EastOutside','FontSize',6,'FontWeight','bold');  
set(get(chandle,'ylabel'),'String','Rain Rate(mm/hr)','FontSize',10,'FontWeight','Bold');  
set(chandle,'YTick',0:5);  
%  s = geoshape(shaperead('landareas','UseGeoCoords',true));  
%  geoshow(s,'DefaultFaceColor','none','DefaultEdgeColor','k');  
%  tightmap
hold on;
k=shaperead('C:\Users\Tanmoyee\Desktop\GFS\wind2\HP_UK.shp');
plot([k.X],[k.Y], 'k:','linewidth','8');
The image coming is attached.
Noe me adding wind vector upon it by quiver(U,V).Then the image is not falling on previous image.How can I solve it.
