Custom Figure Class

You can pass a custom Figure constructor to figure if you want to derive from the default Figure. This simple example creates a figure with a figure title.

from matplotlib.pyplot import figure, show
from matplotlib.figure import Figure


class MyFigure(Figure):
    def __init__(self, *args, **kwargs):
        """
        custom kwarg figtitle is a figure title
        """
        figtitle = kwargs.pop('figtitle', 'hi mom')
        Figure.__init__(self, *args, **kwargs)
        self.text(0.5, 0.95, figtitle, ha='center')


fig = figure(FigureClass=MyFigure, figtitle='my title')
ax = fig.add_subplot(111)
ax.plot([1, 2, 3])

show()
