Parameters

  • var (TransientVariable) – input N-d TransientVariable.

  • xarray (ndarray) – 1d array, x-coordinates.

  • yarray (ndarray) – 1d array, y-coordinates.

Returns

isgeo (bool) –

True if inputs are suitable for geographical plot, False

otherwise.

var (TransientVariable): input <var> with latitude order reversed if

needed.

xx (ndarray): 1d array, use longitude axis of <var> if possible,

<xarray> otherwise

yy (ndarray): 1d array, use latitude axis of <var> if possible,

<yarray> otherwise
