I thought this would be solved by tight_layout (as per [this issue](https://github.com/matplotlib/matplotlib/issues/199) for instance) but this does not seem to be the case, at least for a pie chart.\n\nBelow is a code snippet to reproduce. In fact, tight_layout makes it even worse since it ignores the labels and crops tighter to the pie.\n\nIs there a way around this ?\n\nAm I doing things wrong ?\n\n``` python\n# -*- coding: utf-8 -*-\n\nimport sys\n\nfrom PyQt4 import QtGui\n\nfrom matplotlib.figure import Figure\n\nfrom matplotlib.backends.backend_qt4agg import (\n    FigureCanvasQTAgg as FigureCanvas)\n\nclass MplCanvas(FigureCanvas):\n    \"\"\"Class to represent the FigureCanvas widget\"\"\"\n    def __init__(self):\n\n        # Setup Matplotlib Figure and Axis\n        self.fig = Figure(facecolor=\"white\")\n        self.axes = self.fig.add_subplot(111)\n\n        # Initialization of the canvas\n        super(MplCanvas, self).__init__(self.fig)\n\n        # Define the widget as expandable\n        FigureCanvas.setSizePolicy(self,\n                                   QtGui.QSizePolicy.Expanding,\n                                   QtGui.QSizePolicy.Expanding)\n\n        # Notify the system of updated policy\n        FigureCanvas.updateGeometry(self)\n\n        # Call tight_layout on resize\n        #self.mpl_connect('resize_event', self.fig.tight_layout)\n\nclass MplWidget(QtGui.QWidget):\n    \"\"\"Widget defined in Qt Designer\"\"\"\n    def __init__(self, parent = None):\n\n        super(MplWidget, self).__init__(parent)\n\n        # Set canvas and navigation toolbar\n        self.canvas = MplCanvas()\n\n        # Layout as vertical box\n        self.vbl = QtGui.QVBoxLayout()\n        self.vbl.addWidget(self.canvas)\n        self.setLayout(self.vbl)\n\n\nif __name__ == \"__main__\":\n\n    app = QtGui.QApplication(sys.argv)\n\n    W = MplWidget()\n\n    W.canvas.axes.cla()\n\n    values = [0.2, 0.5, 0.3]\n    labels = ['label',\n              'looooooog label',\n              'very loooooooooooooooooooooooog label'\n             ]\n\n    W.canvas.axes.pie(values, labels=labels)\n    W.canvas.axes.axis('equal')\n\n    W.canvas.fig.tight_layout()\n    W.canvas.draw()\n    W.show()\n\n    sys.exit(app.exec_())\n```\n\nI'm using python 2.7 and Matplotlib 1.4.3~rc1 from Debian experimental.\n","author":{"url":"https://github.com/lafrech","@type":"Person","name":"lafrech"},"datePublished":"2015-03-20T09:53:22.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":12},"url":"https://github.com/4251/matplotlib/issues/4251"}
