Plotting contours of my data onto a map

Is is possible to plot contours of my data (a matrix) onto a map similar to that created by:
geolimits([49 53],[-6 2.8])
geobasemap streets
I get the following error when using contourm:
Error using hggroup Group cannot be a child of GeographicAxes.
Error in internal.mapgraph.HGGroupAdapter (line 62) g = hggroup('Parent',ax);
Error in internal.mapgraph.ContourGroup (line 282) h = h@internal.mapgraph.HGGroupAdapter(args{:});
Error in internal.mapgraph.GeographicContourGroup (line 55) h = h@internal.mapgraph.ContourGroup(varargin{:});
Error in contourm (line 110) h = internal.mapgraph.GeographicContourGroup(ax, Z, R, levelList);
I can plot the data onto a worldmap:
> worldmap([50 52],[-5.7 2.5])
> load coastlines
> plotm(coastlat,coastlon)
> contourm(testlat,testlon,testdat)
However, this map is poor quality as it is not particularly refined. I ideally want to plot on a map like 'geobase streets'.
Any advice on how to plot contours of my data onto the geo map would be apprecied. If this is not possible, then I would like to know if there is a way of improving the quality of map produced by worldmap. Thanks
