Plotting data on world map

I'm trying to plot location specific data on world map. To generate the map I use:

worldmap('World')
load coastlines
plotm(coastlat,coastlon)

Then I have a 1d vector with data, and 1d vector with longitude data and a third 1d vector with latitude data.

Tried plotting the data on world map using the following approach:

for i=1:length(data)
hold all
pcolorm(latitude(i),longitude(i),data(i))
end

colorbar
colormap jet
caxis([min max])

But this doesn't seem to work. I also tried plotm, surfm nothing seem to be working. The data corresponds to rain levels across the globe.
