How to tighten the space of a worldmap plot

I am trying to plot a geophysical variable on a sphere, using the following code:

[lat_grid,lon_grid] = meshgrid(Y,X); % Creating the grid from the vectors of latitude and longitude
load coast;                          
worldmap('World');                   
setm(gca,'Origin',[0 180]);              
geoshow(lat,long);                    
pcolorm(lat_grid,lon_grid,Var);      % plotting the geophysical variable "Var"
colormap('jet');

In the plot I get there is a lot of unnecessary space between the axes and the figure's frame:

I tried to remove space by using:

axis tight;

and then by using:

ax = gca;
ax.Position = [0.0, 0.0, 1.0, 1.0];

but there is still a lot of unwanted space between the actual plot and the figure's frame.

I would like to know how to minimize that space.

Thanks in advance,

Meir.

I think, you would try this code;

xlim([-20000000 20000000])
ylim([-10000000 10000000])

Sorry, it didn't have any effect on my plot.
