Hello Wahabo.
Maybe is better to start with the lower number of imports at the beginning
and add it later, if needed, after you have a working-well initial release.
This code is working for me (I also removed super-class):
import pyqtgraph as pg
import numpy as np
import sys
class Window(pg.Qt.QtGui.QMainWindow):
def __init__(self, parent=None, flags=pg.Qt.QtCore.Qt.WindowFlags()):
pg.Qt.QtGui.QMainWindow.__init__(self, flags=flags)
self.a = []
self.b = []
self.x = []
self.y = []
self.mapper = pg.Qt.QtCore.QSignalMapper()
self.Widget = pg.Qt.QtGui.QWidget()
self.setCentralWidget(self.Widget)
self.Layout_widget = pg.Qt.QtGui.QGridLayout()
self.Widget.setLayout(self.Layout_widget)
self.groupbox = pg.Qt.QtGui.QGroupBox(self.Widget)
# self.groupbox.setCheckable(True)
# self.groupbox.clicked.connect(self.Afficher)
self.groupbox_layout = pg.Qt.QtGui.QVBoxLayout()
self.groupbox.setLayout(self.groupbox_layout)
self.canva = pg.GraphicsWindow()
# self.graph_1 = self.canva.addPlot(title="Basic array plotting")
self.Layout_widget.addWidget(self.groupbox)
self.Layout_widget.addWidget(self.canva)
self.Checkbox = []
for i in range (3):
checkbox = pg.Qt.QtGui.QCheckBox("Capteur {0}".format(i))
checkbox.stateChanged.connect(self.Afficher)
self.Checkbox.append(checkbox)
for i in range(3):
self.groupbox_layout.addWidget(self.Checkbox[i])
self.x1 = np.linspace(0,20,10)
self.y1 = np.arange(0,10)
self.x.append(self.x1)
self.y.append(self.y1)
self.x2 = np.arange(0,10)
self.y2 = np.linspace(0,20,10)
self.x.append(self.x2)
self.y.append(self.y2)
self.x3 = np.random.normal(size=10)
self.y3 = [i**2 for i in range(10)]
self.x.append(self.x3)
self.y.append(self.y3)
def Afficher(self):
self.a = []
b=self.sender()
print(b.text())
self.a.append(b)
for i in range(len(self.a)):
b =
self.canva.addPlot(title="{}".format(self.a[i].text()),row=0,col=i)
self.b.append(b)
for i in range(len(self.b)):
self.b[i].plot(self.x[i],self.y[i])
if __name__ == "__main__":
app = pg.Qt.QtGui.QApplication(sys.argv)
w = Window()
w.show()
sys.exit(app.exec_())
