Matplotlib: pyside

Date:2012-06-10 (last modified), 2011-07-06 (created)

This is a very basic example showing how to display a matplotlib plot within a Qt application using PySide. In case of problems try to change the rcParam entry “backend.qt4” to "PySide" (e.g. by in the matplotlibrc file).

In [ ]:

#!/usr/bin/env python
import sys
import matplotlib
matplotlib.use('Qt4Agg')
import pylab

from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.figure import Figure

from PySide import QtCore, QtGui

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)

    # generate the plot
    fig = Figure(figsize=(600,600), dpi=72, facecolor=(1,1,1), edgecolor=(0,0,0))
    ax = fig.add_subplot(111)
    ax.plot([0,1])
    # generate the canvas to display the plot
    canvas = FigureCanvas(fig)

    win = QtGui.QMainWindow()
    # add the plot canvas to a window
    win.setCentralWidget(canvas)

    win.show()

    sys.exit(app.exec_())
