Pcolor Map showing up blank?

Hi everyone!

I'm trying to plot a map using pcolor, however the map ends up being blank. I'm not really sure what I'm doing wrong? I attached the code below, and an image of the map that my code has been creating.

My code:

%create data
lat=[-90:0.25:90];
lon=[0:0.25:359.75];
smean=rand(1440,721);
figure(121)
worldmap([-90 90], [0 360])
load coastlines
pcolor(lat,lon,smean); hold on
geoshow(coastlat,coastlon,'Color','k'); hold off
h=colorbar;
%h.Label='Difference in SWH measurement (m)';
ylabel(h,'Kw (cm hr-1','FontSize',10);
title('Climatological Mean of Kw for January')

Use pcolorm

%create data
lat=[-90:0.25:90];
lon=[0:0.25:359.75];
smean=rand(1440,721);
figure(121)
worldmap([-90 90], [0 360])
load coastlines
pcolorm(lat,lon,smean); hold on
geoshow(coastlat,coastlon,'Color','k'); hold off
h=colorbar;
%h.Label='Difference in SWH measurement (m)';
ylabel(h,'Kw (cm hr-1','FontSize',10);
