In matplotlib,I can use plt.yticks to set scale as I liked.
def plot(self,data):
''' plot some random stuff '''
plt.figure()
plt.plot(data,'ro')
plt.yticks([1, 2, 3, 4,5,],['Fault 1', 'Fault 2','Fault 3','Fault 4','Fault 5',])
plt.show()
However,when using pyqt5, I have to combile matplotlib with canvas, and it seems it's useless to use yticks.
class Window(QDialog):
def __init__(self, parent=None):
super(Window, self).__init__(parent)
# a figure instance to plot on
self.figure = plt.figure()
# this is the Canvas Widget that displays the `figure`
# it takes the `figure` instance as a parameter to __init__
self.canvas = FigureCanvas(self.figure)
# this is the Navigation widget
# it takes the Canvas widget and a parent
self.toolbar = NavigationToolbar(self.canvas, self)
# Just some button connected to `plot` method
self.button = QtWidgets.QPushButton('Plot')
self.button.clicked.connect(self.plot)
# set the layout
layout = QtWidgets.QVBoxLayout()
layout.addWidget(self.toolbar)
layout.addWidget(self.canvas)
layout.addWidget(self.button)
self.setLayout(layout)
def plot(self,data):
''' plot some random stuff '''
# random data
# data = [random.random() for i in range(10)]
# create an axis
ax = self.figure.add_subplot(111)
# discards the old graph
ax.hold(False)
# plot data
ax.plot(data, '*-')
ax.yticks([1, 2, 3, 4,5,],['Fault 1', 'Fault 2','Fault 3','Fault 4','Fault 5',])
#ax.set_yticks([1, 2, 3, 4,5,],['Fault 1', 'Fault 2','Fault 3','Fault 4','Fault 5',])
# refresh canvas
self.canvas.draw()
Anybody knows how to use the yticks in pyqt5(maybe in canvas)?
