How to successfully add a graph to a GUI using python QT Designer?

[Sean Bellefeuille]

Here is my code...where would I add the graph using pyqtgraph to add it to the graphics view which I called G_view

from PyQt4 import QtCore, QtGui

from pyqtgraph import PlotWidget

try:

    _fromUtf8 = QtCore.QString.fromUtf8

except AttributeError:

    def _fromUtf8(s):

        return s

try:

    _encoding = QtGui.QApplication.UnicodeUTF8

    def _translate(context, text, disambig):

        return QtGui.QApplication.translate(context, text, disambig, _encoding)

except AttributeError:

    def _translate(context, text, disambig):

        return QtGui.QApplication.translate(context, text, disambig)
