 ==================
 
 The :meth:`pygmt.Figure.grdview()` method can plot 3-D surfaces with
-``surftype="s"``. Here, we supply the data as an :class:`xarray.DataArray` with
-the coordinate vectors ``x`` and ``y`` defined. Note that the ``perspective``
-parameter here controls the azimuth and elevation angle of the view. We provide
-a list of two arguments to ``frame`` - the first argument specifies the
-:math:`x`- and :math:`y`-axes frame attributes and the second argument,
-prepended with ``"z"``, specifies the :math:`z`-axis frame attributes.
-Specifying the same scale for the ``projection`` and ``zscale`` parameters
-ensures equal axis scaling. The ``shading`` parameter specifies illumination;
-here we choose an azimuth of 45° with ``shading="+a45"``.
