grid
(draw_grid=True, grid_type='lines', **kwargs)[source]¶ Plot gridlines for both coordinates.
Standard matplotlib appearance options (color, alpha, etc.) can be passed as keyword arguments.
Parameters: draw_grid : bool
Whether to show the gridlines
grid_type : { ‘lines’ | ‘contours’ }
Whether to plot the contours by determining the grid lines in world coordinates and then plotting them in world coordinates (
'lines'
) or by determining the world coordinates at many positions in the image and then drawing contours ('contours'
). The first is recommended for 2-d images, while for 3-d (or higher dimensional) cubes, the'contours'
option is recommended.
