pyqtgraph设置y轴固定范围
class MainW(QMainWindow): def __init__(self, x_list, y_list): super(MainW, self).__init__() self.wdg = QWidget() self.wdg.resize(1000, 600) self.glt = QGridLayout() self.wdg.setLayout(self.glt) self.p3 = pg.PlotWidget(title='goo') pg.setConfigOptions(antialias=True) self.glt.addWidget(self.p3) self.curve = self.p3.plot(pen=QColor(88, 88, 88), name='y1') self.p3.setYRange(400, 800) # 设置y轴范围 self.curve.setData(x_list, y_list) self.setCentralWidget(self.wdg)
显示结果:y轴从400到800
