matplotlib.pyplot.grid

matplotlib.pyplot.grid(b=None, which='major', axis='both', **kwargs) [source]

Turn the axes grids on or off.

Set the axes grids on or off; b is a boolean.

If b is None and len(kwargs)==0, toggle the grid state. If kwargs are supplied, it is assumed that you want a grid and b is thus set to True.

which can be 'major' (default), 'minor', or 'both' to control whether major tick grids, minor tick grids, or both are affected.

axis can be 'both' (default), 'x', or 'y' to control which set of gridlines are drawn.

kwargs are used to set the grid line properties, e.g.,:

ax.grid(color='r', linestyle='-', linewidth=2)
