Help on method tight_layout in module matplotlib.figure:tight_layout(renderer=None, pad=1.08, h_pad=None, w_pad=None, rect=None) method of matplotlib.figure.Figure instance Adjust subplot parameters to give specified padding. Parameters: *pad* : float padding between the figure edge and the edges of subplots, as a fraction of the font-size. *h_pad*, *w_pad* : float padding (height/width) between edges of adjacent subplots. Defaults to `pad_inches`. *rect* : if rect is given, it is interpreted as a rectangle (left, bottom, right, top) in the normalized figure coordinate that the whole subplots area (including labels) will fit into. Default is (0, 0, 1, 1). |
