So they're telling us that we have an x-coordinate of 6. Can only be mapped to a coordinate if a grid_center is defined. By default, when a contour plot is drawn over a map plot, all of the contour plot components, the map filled areas, and the map perimeter are drawn during the "Draw" phase, and the map outlines, grid lines, and map labels are. Geo object which can be used to control the appearance of the base map onto which data is plotted. It is similar to plotting in MATLAB, allowing users full control over fonts, line styles, colors, and axes properties.
