Dear Alejandro,
Many thanks! I use almost the same setup (Spyder 3.2.4, Python 3.5.2
64bits, PyQt5.6 on Windows)
Small thing: "import sys" is missing, I guess.
I tried your code and it seems clear to me, except one point, but I
probably miss a bit of background:
you define "plotexample" as a method in the "MyWindowClass". And run it in
the constructor (well _init__).
When I try to execute then Spyder prompts "undifined name 'plotexample' ".
so I took it out and I am not sure where to call it from here...
Everything else works nicely.
I had to adapt the execution part, otherwise every second run of the
program kills the kernel:
from PyQt5 import uic,QtWidgets,QtGui
import pyqtgraph
import numpy as np
import sys
form_class = uic.loadUiType("Test_Average-GUI.ui")[0]
class MyWindowClass(QtWidgets.QMainWindow,form_class):
def __init__(self, parent=None):
QtWidgets.QMainWindow.__init__(self, parent)
self.setupUi(self)
# here you can properties of your graph widget.... for example:
self.GraphWidgetName.setTitle('My Graph')
self.GraphWidgetName.setLabel('bottom', 'X axis')
self.GraphWidgetName.setLabel('left', 'Y axis')
def plotexample(self):
a=np.array([1,2,3,4,5])
b=np.array([6,7,8,9,10])
self.GraphWidgetName.plot(a,b)
self.GraphWidgetName.showGrid(x=True, y=True)
if __name__=="__main__":
app = QtWidgets.QApplication.instance() #Check for an instance of a
QtWidgets.QApplication, if so use it...
if app is None:
app = QtWidgets.QApplication(sys.argv)
else:
print('QApplication instance already exists: %s' % str(app))
MyWindow = MyWindowClass(None)
MyWindow.show()
app.exec_()
